In Ireland, this plant is quite common. I’m absolutely astonished to see this “carrot” that grows on the lane down by my house so dangerous. Everyone thinks it causes warts so don’t go near it. But it’s so much worse
Orla Mahon if you’re from Ireland you might be confusing it with cow parsley?? It looks similar but is much smaller scale wise (only grows to about a metre tall) and it doesn’t cause the same harm as hogweed. If it is hogweed though in Ireland if you just call your local council and they should come and take it away for you. Round where I live if you tell them there’s hogweed they take it pretty seriously and will come and remove it professionally.
In Czech it's "Bolševník velkolepý". While it's from Russian "bolshoi" (big, large, ...), there is no adjective sounding similar in Czech so it sounds kinda like "Spectacular Bolshevik-maker" which also sounds pretty dangerous.
Hahaha, I just wanted to wirte that it meant that in German too: Bärenklau. My neighbour once had some of these pesty plants in her garden and the seeds flew over and sooner than expected, a giant hogweed sprouted in our garden. We immediately got rid of that dangerous plant. Our neighbour noticed that we were cutting down and uprooting the hog weed and could not believe it. It was such a beautiful plant and she had some in her garden too that she brought from a field where she kept some of her bees. My father told her of the risks and consequences and that she should never touch hogweed because she could get really serious burns by phytophoto reaction. The next day, she came to see my father who is adactor and she really had large burns on her arms and face. The blisters rose like 4cm high and she was in deep pain. What happened? She cut the hogweed without protective gear and was full of sap on all the skin areas that were exposed...
My family almost bought some land here in Germany, until we visited the site and there were just thousands of giant hogweeds or "Riesen-Bärenklau" (literally giant-bear-claw lol) You can imagine - we got the hell outta there.
@@JustNatax3 Yeah you need a herd of sheep. They love the stuff. It takes about two years of grazing all summer to get rid of it though. My city uses sheep quite effectively for this purpose though, better than glyphosate.
Yeah normal hogweed isn't dangerous. Looks about the same, maybe a few metres shorter. Giant hogweed you can't actually pluck, you'll burn your hands something awful. Some sheep breeds will graze on them, especially the wilder breeds. Normal sheep used in commercial settings won't touch them though.
I live in Lithuania, where this plant is a big problem, it is really hard to get rid off and only burning it down seems to be the only efficient way to stop it from popping up again. Also we brought it in not for their appearance, but because we thought they were a good way to feed house animals, but we didn't do enough research beforehand :x
@@warhawkjah it is the case for Sosnowsky's Hogweed, it is very simmilar, just slighly smaller, it was introduced to western Soviet union, while Stalin was in charge, we also have those here too.
Grubiantoll, it's not resistant to RoundUp so it's not THAT annoying. But you have to inject it with a needle, not just spray, and do it in spring, when the plants are still small.
Genesis wrote a song about this thing back in the day: Return of the Giant Hogweed. Great song, pretty accurate as well bar the fact it destroys humanity in the end.
It is called "Sosnowsky's Hogweed" and it is essentially the same thing. There are more uses to the plant, however, than just strange tastes in garden decoration. Still it is nice of Scishow to warn some people.
Kwodlibet what uses are there? As someone in Russia who has heard a bit about the plant, I haven't really heard about its uses apart from the attempt to feed cattle (and the animals wouldn't really eat it cause it was even painful, as far as I remember)
@@atriyakoller136 you can eat some types of this plant, the ones that are not toxic, but it's really hard to distinguish one from another. They are pretty tasty tho
Madd the Sane Yup, hard to live with burned digestive tract. Many years later old meadows are still unusable, because how invasive that plant is. It's mainly a problem in regions where old state run farms introduced it.
It's sounds kinda like Sosnowsky's hogweed (barszcz sosnowskiego -> sosnowsky's borscht). Gift from Soviet Union, it was supposed to be a cow's food. Turns out it was a terrible idea. Plant is sometimes called "Stalin's revenge", since it was introduced during Stalin's (who wasn't exacly known for his kindness or sanity) reign.
well there you go - transitioning legs, or legs that aren't really legs (like men who aren't really women). still, if whales could get out the sea and forage in the landscape, then so be it, but I find it offensive that reference had to made about the whales colour, as if playing the racist card entitles whales to suddenly walk around.
I'm an Upstate New Yorker and my favorite flower is Queen Anne's Lace, also known as wild carrot, and thusly the tiny version of this guy. In my childhood, all the time people would freak out when I brought back bunches of them, because they're identical to giant hogweed, but never grow more than a half foot in diameter. And I'd always have to explain it. To this day I've never seen any Giant Hogweed, which is probably for the best, but still I thin t would be really lovely to look at- just not touch! Also, I may be wrong about this, but I've always been told that hemlock is another carrot relative who is ACTUALLY identical to Queen Anne's Lace, except for the "frock" of leaves beneath the flowers being turned the opposite direction. However, it's much less dangerous than hogweed because I believe it must be ingested to do real harm.
Texadon I don't think hemlock (Poison Hemlock) is a carrot relative, just a look-alike. The only sure way to tell the difference is to smell the root individually. If it smells carroty, it's safe. If it doesn't smell carroty, get rid of it ASAP!
They are taking about Heracleum mantegazzianum not Heracleum sphondylium, sphondylium is not really that much of a problem. Mantegazzianum however is really problematic. Unless you have sheep that wil just eat them again and again. They don't get effected by it but will kill it by just not giving the chance to grow at all.
I live in NC and have very rarely seen giant hogweed, if ever. You may be seeing Queen Anne’s lace, cow parsnip, Angelica, poison hemlock or any of the other parsley family plants we have that are far more common. Exercise caution, but you’re probably fine
I live in Alaska and I came in contact with wild Parsnip. I have permanent scars from the burns the sap caused. Skin blistered like I had a pot of boiling water spilled on me. Been around this stuff my entire life without any problem until this year. Trust me when I say its very unpleasant. Stay away from white sap plants is a good rule to follow.
They look quite a bit different from queen Anne's lace. The umbrell is much larger and more spread than lace, and they're waaaaay bigger. I believe the stems are quite different as well. Hogweed has a woody stem that's somewhat square in cross section if I recall correctly.
@@flamelight7683 it is better to err on the side of caution. I never leave the house without pants tucked into my boots and if I know I'll be heading into the brush I usually throw a long sleeve shirt on, just in case.
we've got hogweed here in New Zealand and it ends up helping native forest more then hindering, most of the NZ native tree have a long growth period so need lots of shelter when they're young, so hogweed bunching up with their big leaves makes it dream for natives to grow and eventually take over i grew up on a farm and there was a hillside covered in hogweed (though we called it whack-burn because you whack it and you get burns) and about 10 years later and there's no hogweed, just thick native bush
@@JeffThePoustman Some of us followed up on the history and mythology. ;) Nursery Cryme is wonderfully educational. Gotta get these nasty things out if New York! Stupid horticulturists. They will kill us all.
Have you guys ever done an episode on resiniferatoxin? Quotes from Wikipedia "pure resiniferatoxin [is] about 500 to 1000 times hotter than pure capsaicin." "Animal experiments suggest that, in humans, ingestion of 10 g may be fatal or cause serious damage to health. It causes severe burning pain in sub-microgram (less than 1/1,000,000th of a gram) quantities when ingested orally. "
This grows all over the place in Alaska, we call is pushki. Every kid has had pushki burns at some point, my brother still has scars on his feet from them. Supposedly it's edible. But when it dies in the fall the woody stalks are left over and they are fun to play with, we used to have pushki sword fights.
The interesting thing is there is a native species that looks VERY similar. It’s called cow parsnip that native people would use to make flutes and even straws.
David Murphy oh no did you use hogweed? I’ve actually made quite a few flutes out of cow parsnip and they work great. (The trick is you have to wait until it’s dry to harvest it).
Micah, yes I did! My chin was one giant blister which continued to weep blood plasma for almost a month afterwards. I still sport a scar on my chin. I did eventually discover that I could nuetralize the irritant by placing the material in the oven at 200 degrees for an hour, and sealing the cut ends with Mod Podge, a water based sealer. Oil based sealer seemed to reactivate it to a degree. I still have a quena and some panpipes I made from it, and the acoustic properties of the material are INCREDIBLE. I would emphatically recommend that anyone NOT work with it, however. But I am stubborn, as I have been making Native American style and World Flutes since 1983. There are a couple pictures of the Poison Hogweed panpipes on my GreyWolf Creations facebook page. 😉
Yes. The cellulose walls surrounded by the hard outer shell, it kind of operates as an onboard amplifier because of the sympathetic vibration, kind of like how a guitar body amplifies the sound of a vibrating string. That was why I played around with it even after I knew the danger. Where I live, Nebraska, we do not have rivercane, sawgrass, or the other traditional hollow plants that easily lend themselves to flutemaking. That's why I was so anxious to work with it. I still have a small supply that I processed that I foolishly have held back just in case I get the "itch" to play with it again. 😂
The Norwegian term for it is "Tromsøpalme" (palm trees of Tromsoe), where (as the red dot on top of Norway indicates) it is an endemic pest after some idiot socialite decided to introduce it to the island in the 1850s. We tend to chop it off at the stem with a machete and burn the roots.
Where I'm from, giant hogweed rarely ever grows taller than a human, the tallest I've seen so far is maybe 1.8 meters. As such, there are some plants with which it can easily be confused. Children usually learn to tell them apart from a very young age, and our foster brother learned it the hard way because he wouldn't listen to my mother. Luckily, he got away with just a long, painful itch, no blisters, but that taught me well to believe people when they said I really shouldn't touch it.
No, this is more like a giant 'Queen Anne's Lace' which is also related to carrots. There's a lot of plants in the carrot family, like Dill and Fennel, etc.
I paused at 2 seconds - haven't watched any of this yet. If there isn't a reference to the Genesis album Nursery Cryme I'm going to smash my computer and set my house on fire.
I live in CT. Found one in my back field this spring...it was young enough that I was able to dig it out with a shovel and medical gloves I bought from a vet...the type that go all the way up to your shoulders for going into the cow it's self...wore a hazmat suit too..with full face/body protection. I've got a flower collecting 7 year old and no amount of telling her how dangerous that plant is would keep her away from it. I called DEEP and several other environmental places and they told me they'd be out when they could. I wait a week then went for it. If I ended up burned from the sap it would suck, but I'd handle it. My children however can not avoid the sun due to sports and school. I certainly couldn't let it linger for the state to come take care of it. About a month after I dug it up and stuck it's roots in a bucket of vinegar they came to take care of it. I handed them the 5 gallon bucket with the dead plant in it then pointed them to the spot that it was growing. They sprayed an herbicide back there and now I've got a huge dead patch where not even the rushes or cattails grow anymore. They killed off my wetlands growth.
My first intro to this hellish plant waswhn I first moved to Ireland. There was this beautiful tree growing in a lovely debilitated building behind in the garden of my apartment. I could see it was taking over and would further destroy the building so thought I'd cut it down. Took my saw, took a good look at it and thought, nah, there's just too much of it. Thank goodness!!
I have had the sap from this stuff on my legs.. Was building a deck on a very hot sunny day here in WA and the home owner was riding around on his tractor and cut the crap out of them. I walked through it in shorts. and by the next day my legs were all blistered up and burning. Wasn't pleasant
@@pebblepod30 My sister ended up with blisters from it too. We were working on our aunt's yard and had no idea what the plant was until the city sent a notice about them. There just isn't a lot of awareness out there compared to more common invasive plants. (In this part of WA we mostly talk about English Ivy and good ol' Himalayan Blackberry.) But I saw a pamphlet about giant hogweed just a few hours before watching this video, so someone must be getting awareness out there.
@@pebblepod30 chances are he had no idea. He had a lot of land and there are so many plants crowded everywhere around here itd be hard to notice one or two of these in a young stage before they got several feet taller than the tall grass. Sure wasn't a pleasant experience. But it was a decent paying gig
Fun fact: Oregon is like Australia but with carrots. Poison hemlock. Water hemlock. Queen Anne's lace. Cow parsnips. Giant hogweed. All five members of the feral carrot family live here, and only one won't try to brutally murder you. Don't touch a tall white-flowered plant unless you're absolutely sure it's Queen Anne's lace and not one of the 'ouch carrots.'
@@helentee9863 Cow parsley and cow parsnips are the same, but this is a good point to bring up. They can be safe with the proper precautions and some individuals don't produce a substantial amount of phototoxins, but it's still advised to steer clear of rivers after flash floods because they tend to initiate mass germination of cow parsnips.
@@RosettaAceAlmaak thanks for the information. I wasn't sure if they were the same, as in the uk we only seem to talk of cow parsley. I was warned as a child to be careful of cow parsley, though possibly as much to keep me away from hogweed as anything. It's pretty common over here unfortunately
It is dangerous even when it's dead! The irritant is a vessicant oil which is still active when the chlorophyll leaves the plant. I am a flutemaker, and first encountered this hollow stalked plant in the fall around 1997. After making some flutes from it, I got severe blistering on my chin, which continued to weep blood plasma for almost a month afterwards. My chin is still scarred.
I remember when I was little my neighbor would give me 25 cents to bring her a bunch of hogweed stocks, after a few times my hands eventually got burns on them. I didn't associate the burns with the plants, I was still young and couldn't put the pieces together quite yet. Fast forward a few weeks and some of my friends had suffered the same fate, for 25 cents we had been bringing her hogweed stocks. Turns out she was an abusive mental case. Shortly after all this occurred she got arrested for breaking her granddaughters left arm and both legs while beating and throwing her against a wall. Just remember the nice old lady next door might not be so nice after all .
I'm a Long Islander, and during my 28 years worth of experience hiking through the woods, rural neighbourhoods, nature trails, and beach combing, I don't recall ever seeing Giant Hogweed. Especially considering how tall they grow. I have seen plants that bare a similar resemblance, the only difference being their height. These plants I'm refering to I've seen along the side of lakes which lead to the Great South Bay, and near marshland. These plants stand at a height of 1 1/2 to 2 feet tall. When I go hiking I bring a natural souveniour or two home with me, sometimes this includes flowers, because doing this helps eleviate depression. I've considered bringing home the plants I've refered to, however if these flowers actually are juvenile Giant Hogweed plants then I'm leaving them alone!
I live in England and my daughter was affected by hogweed - she had huge blisters all over her arms. She was 6 or 7 at the time. Thankfully it healed up quickly without leaving any scars - but worrying at the time.
I can support this warning! Where I live (The Netherlands) there is also an infestation of this awful plant. I went once o holiday with family and one of the members of the company, a 10 year child, suddenly got almost all over his body 3rd degree "burns". We had to return home. Turns out he had been playing a year earlier in a bush of these plants (whitch we call "Giant Bearclaw).
@@expertoflizardcorrugation3967 yes, thank you for the concern. That all happened about 10 years ago. He got burn medication and as soon as he stayed inside it cleared. Eventualy we had to return home, shortening our vacation. I havent seen him now for 5 years, but a couple of years after the mishap he hadn't symptoms anymore. Terrible plant.
The public reporting service and public database for invasive species is called EDDMapS, you can even get an app for your phone that allows to take photos and report the location at the same time. TBH, contacting your nearby environmental authority probably wont do you good: they usually have their hands full with their current projects. If you report to the public database, everyone can see it.
We have them in Lithuania too. They were introduced as a possible plant for animal feed. They're called Sasnovsky's beetroots and they're a huge menace. I think it's one of the worst ways to go down in history, by associating your name with something everybody unanimously hates
I'm from the UK and where i lived when i was younger, there was this river that often has/had giant hogsweed. I remember my mum when i was younger teaching me the difference between this common plant that we have that looks similar to giants hogsweed called cows parsley and her saying "when in doubt over it being cows parsley or giant hogsweed, do not touch". It's also interesting that you call it giant hogweed, because everyone i know calls it giant hogsweed with an s
Another plant that looks is often victimized as a result is "Queen Ann's Lace", which has a very similar looking flower and freaks out a lot of uninformed people. There are several distinctions though. Size, flower pedals and leaves can all be distinguished, but the most striking difference is a tiny black dot that the -sometimes- get in the middle of the crown of flowers. It's actually a very dark purple flower, but isn't always there.
It's called "reuzenberenklauw" (giant bear claw) where I live. As kids we used to make sticks out of the stem of the plant and hit eachother with them. There was this island in our local park that was completely filled with giant hogweed. It was a great place for hide and seek, because the plants were enormous and there were so many of them that you were completely invisible to anyone not on the island.
It might be hard to understand why gardeners brought such a horrific plant around the world. I mean... it was during the victorian era IIRC. The time where people boiled themselves to death in their bath tubs. The time where bakers put Plaster of Paris in bread, lead in sweets to colour them and borax in spoiled milk to cover the taste.
Great lyric: Turn and run! Nothing can stop them, Around every river and canal their power is growing. Stamp them out! We must destroy them, They infiltrate each city with their thick dark warning odour. They are invincible, They seem immune to all our herbicidal battering. Long ago in the russian hills, A victorian explorer found the regal hogweed by a marsh, He captured it and brought it home. Botanical creature stirs, seeking revenge. Royal beast did not forget. He came home to london, And made a present of the hogweed to the royal gardens at kew. Waste no time! They are approaching. Hurry now, we must protect ourselves and find some shelter Strike by night! They are defenceless. They all need the sun to photosensitize their venom. Still they're invincible, Still they're immune to all our herbicidal battering. Fashionable country gentlemen had some cultivated wild gardens, In which they innocently planted the giant hogweed throughout the land. Botanical creature stirs, seeking revenge. Royal beast did not forget. Soon they escaped, spreading their seed, Preparing for an onslaught, threatening the human race. Mighty hogweed is avenged. Human bodies soon will know our anger. Kill them with your hogweed hairs Heracleum mantegazziani
I saw some of these for the first time a while ago on the banks of the River Mersey in the UK. They were far,far bigger then i was expecting! luckly the local council had managed to do something to them as they were all dying away. This video was great! i had no idea they were relatives of the carrot 0_o
In Denmark we call them "Giant Bear Claw", horrible encounter if you accidentally get in contact with it (worst day of my life and I only got a bit on my hand!)
Japanese Knotweed is a huge problem in the U.S. too. It doesn't cause dermatitis, but it takes over large areas of land and can even grow through paved roads and house foundations.
my friend had some in his yard and his father had to buy disposable hazmat suits and battle with it for over a year to eradicate it. it grew through cardboard, plastic, and even grew around cement that was poured on it! it can lay dormant for years and come up as soon as it has a way to get to the surface. truly a menace
Wild Parsnip in Alaska does some of the same things, with the sunlight and burning. We call it "gingerbane", because I didn't already have enough to fear from direct sunlight.
I had some next to my garden when I was little. They are very invasive, but I never got hurt around them. I was careful, as my parents told me they were a little poisonous, but I never had any problem when I went into contact with them, or even removed them...
I remember touching a plant when I was young that that caused an extremely sharp and instant pain on a small part of the top of my hand. Never knew why or exactly what I touched but now it makes a bit more sense
I grew these devil plants as a fence covering in an old property of mine in Texas. I would have loved to have seen someone try to break in lol the screams would have been hilarious!!
We have these in SW Ontario. The best way to get rid of them in ecosystems is carefully applying glyphosate to individual plants while wearing protective clothing.
Ayyy, it's Barszcz Sosnowskiego (direct translation to English is Sosnowsky's Borsch, but it's real English name is Sosnowsky's hogweed), also known as Stalin's Revenge! EDIT: as it turns out, it's not, Heracleum sosnowskyi is what I meant, and the video is about Heracleum mantegazzianum. They're very similar thought.
I grow carrots for food and flowers. They look just like this hog-plant but way smaller; around 2 meters in my yard. I’ve never noticed any issues with its sap, but it’s going to be on my mind now.
I'm from Sweden. As children maybe ages 7-9 me an my friend used to spend the summers and springs destroying these plants with sticks. We chopped them off and stuck the stick through the middle of the trunk. One time we poisoned them with detergent. It was great fun, we knew they were dangerous but not to this extent
The way it burns you reminds me of that trick where you put a circle of black sharpie on your skin then put your phone camera flash directly on the spot. Major difference being that i doubt you'll get third degree burns from the sharpie trick.
There is one or two of them at our harbor and no one else was brave enough to get rid of them so I went almost full spacesuit in the middle of a drought and cut that up. Somehow it could grown just fine in seawater and sand, now I have a job to do there for the next few years XD
In some places, they use sheep to take care of them, because the sheep aren't really bothered by them, but will eat them happily. But the same plant can keep sprouting again for about 10 seasons if it's not allowed to produce its seeds. If allowed to produce them, the plant will die off. So there's 2 other ways to get rid of it: 1 - Dig most of its root up to kill the plant. 2 - Let the plant produce its seeds and then cut away the flower/seed heads and pack them away for destruction.
my brother got second-degree burns last year from what he believes may have been a lemon. Thank you, lemons, for teaching us about phytophotodermatitis so that I knew what this video was talking about.
As an ecological land manager, I really appreciate you highlighting this invasive species, and bringing the science to it. You could have scienced a little harder by including the term "allelopathic"... and a mention that wild parsnip (Pastinaca sativa), which is much more abundant in North America anyway, also causes phytophotodermatitis, would have been worthwhile.
Here in belgium we call it 'bears claw' and we have another plant that looks exactly like it but is completely harmless. You never know which one you're dealing with
Toen ik jong was plukte ik deze (je vond deze zo wat overal in graskant) ik vroeg mij al af wat zo gevaarlijk was aan deze plant. Kwist niet dat er 2soorten bestonden... Vindt hier in België de gevaarlijke variant ook???

It only looks like cow parsley briefly. Right before it turns into the giant that ate Dublin
The Dutch word for it literally translates into "bearclaw" which sounds as dangerous as it actually is.
In Danish the plant is named 'bjørneklo' which also translates to bearclaw.
In Czech it's "Bolševník velkolepý". While it's from Russian "bolshoi" (big, large, ...), there is no adjective sounding similar in Czech so it sounds kinda like "Spectacular Bolshevik-maker" which also sounds pretty dangerous.

It's sounds kinda like Sosnowsky's hogweed (barszcz sosnowskiego -> sosnowsky's borscht). Gift from Soviet Union, it was supposed to be a cow's food. Turns out it was a terrible idea. Plant is sometimes called "Stalin's revenge", since it was introduced during Stalin's (who wasn't exacly known for his kindness or sanity) reign.
Only Stalin would import a toxic plant for food.
The plants are actually related.
Yes, they look very similar. I think soviets saw its growing power and tried to make it useful. Ended up spreading it even more
As a landscaper and wild forager, this is essentially my white whale and worst enemy.
lol you don't get whales on the landscape, no matter how wildly you forage for them - they just can't get there, they haven't got legs 😁
Spray with weed killer, remove when dried out, kill before the seeds are formed. Or cover up real well.....
@@willemkossen no just let sheeps deal with it. Works even better and you have nothing left besites some sheep manure.
BlueDiamond, yeah, that guy is a moron.
Just because some whales are transitioning doesn't mean they aren't beautiful and sexy.
well there you go - transitioning legs, or legs that aren't really legs (like men who aren't really women). still, if whales could get out the sea and forage in the landscape, then so be it, but I find it offensive that reference had to made about the whales colour, as if playing the racist card entitles whales to suddenly walk around.
I'm an Upstate New Yorker and my favorite flower is Queen Anne's Lace, also known as wild carrot, and thusly the tiny version of this guy. In my childhood, all the time people would freak out when I brought back bunches of them, because they're identical to giant hogweed, but never grow more than a half foot in diameter. And I'd always have to explain it. To this day I've never seen any Giant Hogweed, which is probably for the best, but still I thin t would be really lovely to look at- just not touch!
Also, I may be wrong about this, but I've always been told that hemlock is another carrot relative who is ACTUALLY identical to Queen Anne's Lace, except for the "frock" of leaves beneath the flowers being turned the opposite direction. However, it's much less dangerous than hogweed because I believe it must be ingested to do real harm.
Lol queen anne's lace is my favorite too. My first thoght when i saw guant hogweed was that it looks like a giant queen annes lace!
Texadon
I don't think hemlock (Poison Hemlock) is a carrot relative, just a look-alike. The only sure way to tell the difference is to smell the root individually. If it smells carroty, it's safe. If it doesn't smell carroty, get rid of it ASAP!
Trevor H Ohhh interesting. Thanks for the info!
In Dutch, these infamous plants are known as berenklauw, or bear's claw.
this is about "Reuze" version, wich is a pain in the ass the remove, worked as a gardener and had to remove some
Same in German. Riesen-Bärenklau
It's also called bearclaw (bjørneklo) in Danish.
I call them kanker plant
They are taking about Heracleum mantegazzianum not Heracleum sphondylium, sphondylium is not really that much of a problem. Mantegazzianum however is really problematic. Unless you have sheep that wil just eat them again and again. They don't get effected by it but will kill it by just not giving the chance to grow at all.
And when it does, it doesn't *carrot* all 😅🥕

Hello.
Hey there
Carrot puns?! I'm rooting for you!
Pfft I used to be annoyed by puns in scishow comments but now they’re kind of growing on me. PS I love your channel Tom
We have it in Ireland as well. Widespread around rivers. A child was hospitalized recently with 3rd degree burns.
I live in in Northern Norway, and it is really remarkable to see these plants grow up to 3metres in 3-4months. Never get used to it
I live in northern North Carolina and I've seen those around my house, never realized how dangerous they can be.
MUCH better to find out here first.
I live around there, too, but haven't seen any yet. Queen Anne's Lace looks similar, though.
several plants look rather similar, look for the tells... if any match perfectly see if you can get them removed
I live in NC and have very rarely seen giant hogweed, if ever. You may be seeing Queen Anne’s lace, cow parsnip, Angelica, poison hemlock or any of the other parsley family plants we have that are far more common. Exercise caution, but you’re probably fine
Now the Genesis song "return of the giant hogweed" makes sense
I live in Alaska and I came in contact with wild Parsnip. I have permanent scars from the burns the sap caused. Skin blistered like I had a pot of boiling water spilled on me. Been around this stuff my entire life without any problem until this year. Trust me when I say its very unpleasant. Stay away from white sap plants is a good rule to follow.
Where I live, Queen Anne’s Lace grows naturally, but it’s a pain to have to worry if that innocent looking plant is actually a Giant Hogweed
Never saw Queen Anne's Lace more than a few feet tall.
They look quite a bit different from queen Anne's lace. The umbrell is much larger and more spread than lace, and they're waaaaay bigger.
I believe the stems are quite different as well. Hogweed has a woody stem that's somewhat square in cross section if I recall correctly.
I’m still paranoid it could be a young Hogweed, and not just Lace
@@flamelight7683 it is better to err on the side of caution. I never leave the house without pants tucked into my boots and if I know I'll be heading into the brush I usually throw a long sleeve shirt on, just in case.
@@flamelight7683 the leaves are quite a bit different as well, and hogweed doesnt have that little black flower in the middle
Did you hear about the carrot detective?
He got to the root of every case.
*ba dum tss* 🥁 😂
That was a really good and informative episode! I'll definitely be on the lookout for hogweed!
we've got hogweed here in New Zealand and it ends up helping native forest more then hindering, most of the NZ native tree have a long growth period so need lots of shelter when they're young, so hogweed bunching up with their big leaves makes it dream for natives to grow and eventually take over
i grew up on a farm and there was a hillside covered in hogweed (though we called it whack-burn because you whack it and you get burns) and about 10 years later and there's no hogweed, just thick native bush
What genius brought Giant Hogweed to the USA? HOLY MOLY! Don't people listen to Genesis?

Have you guys ever done an episode on resiniferatoxin?
Quotes from Wikipedia
"pure resiniferatoxin [is] about 500 to 1000 times hotter than pure capsaicin."
"Animal experiments suggest that, in humans, ingestion of 10 g may be fatal or cause serious damage to health. It causes severe burning pain in sub-microgram (less than 1/1,000,000th of a gram) quantities when ingested orally. "
Wow, that is not a nice way to go!
"Animal experiments suggest that..." RIP
This grows all over the place in Alaska, we call is pushki. Every kid has had pushki burns at some point, my brother still has scars on his feet from them. Supposedly it's edible. But when it dies in the fall the woody stalks are left over and they are fun to play with, we used to have pushki sword fights.
cool... not fun but cool
The interesting thing is there is a native species that looks VERY similar. It’s called cow parsnip that native people would use to make flutes and even straws.
That's what I thought it was when I made some flutes from it years ago. HUGE mistake!
David Murphy oh no did you use hogweed? I’ve actually made quite a few flutes out of cow parsnip and they work great. (The trick is you have to wait until it’s dry to harvest it).
Micah, yes I did! My chin was one giant blister which continued to weep blood plasma for almost a month afterwards. I still sport a scar on my chin. I did eventually discover that I could nuetralize the irritant by placing the material in the oven at 200 degrees for an hour, and sealing the cut ends with Mod Podge, a water based sealer. Oil based sealer seemed to reactivate it to a degree. I still have a quena and some panpipes I made from it, and the acoustic properties of the material are INCREDIBLE. I would emphatically recommend that anyone NOT work with it, however. But I am stubborn, as I have been making Native American style and World Flutes since 1983. There are a couple pictures of the Poison Hogweed panpipes on my GreyWolf Creations facebook page. 😉
David Murphy damn that sucks! Hmm I’ll have to check your page out. I love the sound they make as well, nothing quite has the same sound...
Yes. The cellulose walls surrounded by the hard outer shell, it kind of operates as an onboard amplifier because of the sympathetic vibration, kind of like how a guitar body amplifies the sound of a vibrating string. That was why I played around with it even after I knew the danger. Where I live, Nebraska, we do not have rivercane, sawgrass, or the other traditional hollow plants that easily lend themselves to flutemaking. That's why I was so anxious to work with it. I still have a small supply that I processed that I foolishly have held back just in case I get the "itch" to play with it again. 😂
Are the skin lesions caused by the giant hogweed a type of wart?
If so, they would be Hogwarts.
Damn you.
Get out
Are you here all week?
OMG yes hahaha.
Master Therion OMG lol
The Norwegian term for it is "Tromsøpalme" (palm trees of Tromsoe), where (as the red dot on top of Norway indicates) it is an endemic pest after some idiot socialite decided to introduce it to the island in the 1850s. We tend to chop it off at the stem with a machete and burn the roots.
Tromsøpalme is a different species (Heracleum tromsoensis), although they are very similar to Heracleum mantegazzianum
Turn and run! Nothing can stop them!
Sorry, I got carried away by Genesis.
Where I'm from, giant hogweed rarely ever grows taller than a human, the tallest I've seen so far is maybe 1.8 meters. As such, there are some plants with which it can easily be confused. Children usually learn to tell them apart from a very young age, and our foster brother learned it the hard way because he wouldn't listen to my mother. Luckily, he got away with just a long, painful itch, no blisters, but that taught me well to believe people when they said I really shouldn't touch it.
BUT IS THERE A GIANT CARROT UNDERGROUND
Alexei S The real question.
GASP
Doki Doki
No, this is more like a giant 'Queen Anne's Lace' which is also related to carrots. There's a lot of plants in the carrot family, like Dill and Fennel, etc.
Wait, I am thinking of Courage the cowardly dog. Ooh that explode carrot, yup jokes.
I paused at 2 seconds - haven't watched any of this yet. If there isn't a reference to the Genesis album Nursery Cryme I'm going to smash my computer and set my house on fire.

I live in CT. Found one in my back field this spring...it was young enough that I was able to dig it out with a shovel and medical gloves I bought from a vet...the type that go all the way up to your shoulders for going into the cow it's self...wore a hazmat suit too..with full face/body protection. I've got a flower collecting 7 year old and no amount of telling her how dangerous that plant is would keep her away from it. I called DEEP and several other environmental places and they told me they'd be out when they could. I wait a week then went for it. If I ended up burned from the sap it would suck, but I'd handle it. My children however can not avoid the sun due to sports and school. I certainly couldn't let it linger for the state to come take care of it. About a month after I dug it up and stuck it's roots in a bucket of vinegar they came to take care of it. I handed them the 5 gallon bucket with the dead plant in it then pointed them to the spot that it was growing. They sprayed an herbicide back there and now I've got a huge dead patch where not even the rushes or cattails grow anymore. They killed off my wetlands growth.
the plant is really hardy, nothing less than the fires of hell will kill it XD
Who know "Genesis - The return of the giant hogweed"
My first intro to this hellish plant waswhn I first moved to Ireland. There was this beautiful tree growing in a lovely debilitated building behind in the garden of my apartment. I could see it was taking over and would further destroy the building so thought I'd cut it down. Took my saw, took a good look at it and thought, nah, there's just too much of it. Thank goodness!!
So invasive, the band Genesis wrote an eight minute long song about it.
There is an early Genesis song about the Giant Hogweed. The song focused on the invasive aspect of the plant.
I have had the sap from this stuff on my legs.. Was building a deck on a very hot sunny day here in WA and the home owner was riding around on his tractor and cut the crap out of them. I walked through it in shorts. and by the next day my legs were all blistered up and burning. Wasn't pleasant
J Blob
And he didn't tell you about it???!
Well obviously he didnt know that would cause harm
@@pebblepod30
My sister ended up with blisters from it too. We were working on our aunt's yard and had no idea what the plant was until the city sent a notice about them. There just isn't a lot of awareness out there compared to more common invasive plants. (In this part of WA we mostly talk about English Ivy and good ol' Himalayan Blackberry.)
But I saw a pamphlet about giant hogweed just a few hours before watching this video, so someone must be getting awareness out there.
home owner should have warned you about walking through the area if he had known they were there
@@pebblepod30 chances are he had no idea. He had a lot of land and there are so many plants crowded everywhere around here itd be hard to notice one or two of these in a young stage before they got several feet taller than the tall grass.
Sure wasn't a pleasant experience. But it was a decent paying gig
Fun fact: Oregon is like Australia but with carrots.
Poison hemlock.
Water hemlock.
Queen Anne's lace.
Cow parsnips.
Giant hogweed.
All five members of the feral carrot family live here, and only one won't try to brutally murder you. Don't touch a tall white-flowered plant unless you're absolutely sure it's Queen Anne's lace and not one of the 'ouch carrots.'
I'm pretty sure hemlock will try to kill you. So will Hogweed.
Cow parsley.
Also inedible,prickly, irritant, but not highly poisonous like hogweed
@@helentee9863 Cow parsley and cow parsnips are the same, but this is a good point to bring up. They can be safe with the proper precautions and some individuals don't produce a substantial amount of phototoxins, but it's still advised to steer clear of rivers after flash floods because they tend to initiate mass germination of cow parsnips.
@@RosettaAceAlmaak thanks for the information.
I wasn't sure if they were the same, as in the uk we only seem to talk of cow parsley.
I was warned as a child to be careful of cow parsley, though possibly as much to keep me away from hogweed as anything. It's pretty common over here unfortunately
I thought hog weed was how harry potter got stoned.
Now, it's how he got Hogwarts
Hogweed: what happens when you hydroponically grow mandrakes and air dry them for a month. . . In mason jars. . .
It is dangerous even when it's dead! The irritant is a vessicant oil which is still active when the chlorophyll leaves the plant. I am a flutemaker, and first encountered this hollow stalked plant in the fall around 1997. After making some flutes from it, I got severe blistering on my chin, which continued to weep blood plasma for almost a month afterwards. My chin is still scarred.
Giant hog weed isn't even the worst plant in that family.
Celery is far worse.
no one believes me when i tell them that veggies are evil
I remember when I was little my neighbor would give me 25 cents to bring her a bunch of hogweed stocks, after a few times my hands eventually got burns on them. I didn't associate the burns with the plants, I was still young and couldn't put the pieces together quite yet. Fast forward a few weeks and some of my friends had suffered the same fate, for 25 cents we had been bringing her hogweed stocks.
Turns out she was an abusive mental case. Shortly after all this occurred she got arrested for breaking her granddaughters left arm and both legs while beating and throwing her against a wall. Just remember the nice old lady next door might not be so nice after all .
I’ll use these to get better eyesight

I'm a Long Islander, and during my 28 years worth of experience hiking through the woods, rural neighbourhoods, nature trails, and beach combing, I don't recall ever seeing Giant Hogweed. Especially considering how tall they grow. I have seen plants that bare a similar resemblance, the only difference being their height. These plants I'm refering to I've seen along the side of lakes which lead to the Great South Bay, and near marshland. These plants stand at a height of 1 1/2 to 2 feet tall.
When I go hiking I bring a natural souveniour or two home with me, sometimes this includes flowers, because doing this helps eleviate depression. I've considered bringing home the plants I've refered to, however if these flowers actually are juvenile Giant Hogweed plants then I'm leaving them alone!
Hans get the flamethrower
Better not
Would not recommend. Burning them spreads poison into the air, turning people what is akin to vampires: burning in sunlight.
I live in England and my daughter was affected by hogweed - she had huge blisters all over her arms. She was 6 or 7 at the time. Thankfully it healed up quickly without leaving any scars - but worrying at the time.
I think it’s funny how plants can be “aggressive”
It's like a prius driver being aggressive...not intimidating but could be deadly still.🤔😃
I can support this warning! Where I live (The Netherlands) there is also an infestation of this awful plant. I went once o holiday with family and one of the members of the company, a 10 year child, suddenly got almost all over his body 3rd degree "burns". We had to return home.
Turns out he had been playing a year earlier in a bush of these plants (whitch we call "Giant Bearclaw).
is the kid okay? that had to be painful
@@expertoflizardcorrugation3967 yes, thank you for the concern. That all happened about 10 years ago.
He got burn medication and as soon as he stayed inside it cleared. Eventualy we had to return home, shortening our vacation.
I havent seen him now for 5 years, but a couple of years after the mishap he hadn't symptoms anymore.
Terrible plant.
Great even plants are now violating the Geneva Convention!
they didn't sign it so they feel compelled to laugh at its restrictions
The public reporting service and public database for invasive species is called EDDMapS, you can even get an app for your phone that allows to take photos and report the location at the same time.
TBH, contacting your nearby environmental authority probably wont do you good: they usually have their hands full with their current projects. If you report to the public database, everyone can see it.
Hehe hogweed hehe
Sorta resembles "Queen Ann's Lace" in the flower head. Queen Ann's Lace doesn't get very tall.
We have them in Lithuania too. They were introduced as a possible plant for animal feed. They're called Sasnovsky's beetroots and they're a huge menace. I think it's one of the worst ways to go down in history, by associating your name with something everybody unanimously hates
I'm from the UK and where i lived when i was younger, there was this river that often has/had giant hogsweed. I remember my mum when i was younger teaching me the difference between this common plant that we have that looks similar to giants hogsweed called cows parsley and her saying "when in doubt over it being cows parsley or giant hogsweed, do not touch". It's also interesting that you call it giant hogweed, because everyone i know calls it giant hogsweed with an s
Another plant that looks is often victimized as a result is "Queen Ann's Lace", which has a very similar looking flower and freaks out a lot of uninformed people. There are several distinctions though. Size, flower pedals and leaves can all be distinguished, but the most striking difference is a tiny black dot that the -sometimes- get in the middle of the crown of flowers. It's actually a very dark purple flower, but isn't always there.
It's called "reuzenberenklauw" (giant bear claw) where I live. As kids we used to make sticks out of the stem of the plant and hit eachother with them. There was this island in our local park that was completely filled with giant hogweed. It was a great place for hide and seek, because the plants were enormous and there were so many of them that you were completely invisible to anyone not on the island.
We have a lot of that stuff in Northern Norway, the plant has been blacklisted, its a nightmare to get it away-
It might be hard to understand why gardeners brought such a horrific plant around the world.
I mean... it was during the victorian era IIRC. The time where people boiled themselves to death in their bath tubs. The time where bakers put Plaster of Paris in bread, lead in sweets to colour them and borax in spoiled milk to cover the taste.
I urge you all to listen to The Return Of The Giant Hogweed by Genesis. That plant was a menace back in the 70's too. Plus it's a great song.
Great lyric:
Turn and run!
Nothing can stop them,
Around every river and canal their power is growing.
Stamp them out!
We must destroy them,
They infiltrate each city with their thick dark warning odour.
They are invincible,
They seem immune to all our herbicidal battering.
Long ago in the russian hills,
A victorian explorer found the regal hogweed by a marsh,
He captured it and brought it home.
Botanical creature stirs, seeking revenge.
Royal beast did not forget.
He came home to london,
And made a present of the hogweed to the royal gardens at kew.
Waste no time!
They are approaching.
Hurry now, we must protect ourselves and find some shelter
Strike by night!
They are defenceless.
They all need the sun to photosensitize their venom.
Still they're invincible,
Still they're immune to all our herbicidal battering.
Fashionable country gentlemen had some cultivated wild gardens,
In which they innocently planted the giant hogweed throughout the land.
Botanical creature stirs, seeking revenge.
Royal beast did not forget.
Soon they escaped, spreading their seed,
Preparing for an onslaught, threatening the human race.
Mighty hogweed is avenged.
Human bodies soon will know our anger.
Kill them with your hogweed hairs
Heracleum mantegazziani
I saw some of these for the first time a while ago on the banks of the River Mersey in the UK. They were far,far bigger then i was expecting! luckly the local council had managed to do something to them as they were all dying away.
This video was great! i had no idea they were relatives of the carrot 0_o
In Denmark we call them "Giant Bear Claw", horrible encounter if you accidentally get in contact with it (worst day of my life and I only got a bit on my hand!)
Japanese Knotweed is a huge problem in the U.S. too. It doesn't cause dermatitis, but it takes over large areas of land and can even grow through paved roads and house foundations.
This use to be a problem in MN on the road side but they went on a mission to get rid of them along with yellow itch weeds.
So this is what the "return if the giant hogweed" by Genesis is about. Creepy.
my friend had some in his yard and his father had to buy disposable hazmat suits and battle with it for over a year to eradicate it. it grew through cardboard, plastic, and even grew around cement that was poured on it! it can lay dormant for years and come up as soon as it has a way to get to the surface. truly a menace
Wild Parsnip in Alaska does some of the same things, with the sunlight and burning. We call it "gingerbane", because I didn't already have enough to fear from direct sunlight.
I had some next to my garden when I was little. They are very invasive, but I never got hurt around them. I was careful, as my parents told me they were a little poisonous, but I never had any problem when I went into contact with them, or even removed them...
*Giant hogweed? Just give the teachers guns.*
I remember touching a plant when I was young that that caused an extremely sharp and instant pain on a small part of the top of my hand. Never knew why or exactly what I touched but now it makes a bit more sense
I was having fun in a T-shirt and short pants with a brush cutter. Then I came across a few of these...
I grew these devil plants as a fence covering in an old property of mine in Texas. I would have loved to have seen someone try to break in lol the screams would have been hilarious!!
I’m afraid of only a few things... giant hogweed is one of them.
I just saw the words 'giant' and 'weed' and thought this would be a video about something awesome
There's a ton of this in Scotland. Apparently when it goes dry and hollow you can smoke it
it grows all around Sudetenland (today's Czech Republic) in the abandoned villages, which makes it even more scary and apocalyptic-looking
We have these in SW Ontario. The best way to get rid of them in ecosystems is carefully applying glyphosate to individual plants while wearing protective clothing.
Ayyy, it's Barszcz Sosnowskiego (direct translation to English is Sosnowsky's Borsch, but it's real English name is Sosnowsky's hogweed), also known as Stalin's Revenge!
EDIT: as it turns out, it's not, Heracleum sosnowskyi is what I meant, and the video is about Heracleum mantegazzianum. They're very similar thought.
I grow carrots for food and flowers. They look just like this hog-plant but way smaller; around 2 meters in my yard.
I’ve never noticed any issues with its sap, but it’s going to be on my mind now.
Was not aware that it was related to carrots, thanks.
We get warnings in the news to be on the lookout for these every Summer.
I'm from Sweden. As children maybe ages 7-9 me an my friend used to spend the summers and springs destroying these plants with sticks. We chopped them off and stuck the stick through the middle of the trunk. One time we poisoned them with detergent. It was great fun, we knew they were dangerous but not to this extent
Anyone else think "Giant Hogweed" sounds like something you would use to make a potion?
The way it burns you reminds me of that trick where you put a circle of black sharpie on your skin then put your phone camera flash directly on the spot. Major difference being that i doubt you'll get third degree burns from the sharpie trick.
There is one or two of them at our harbor and no one else was brave enough to get rid of them so I went almost full spacesuit in the middle of a drought and cut that up. Somehow it could grown just fine in seawater and sand, now I have a job to do there for the next few years XD
In some places, they use sheep to take care of them, because the sheep aren't really bothered by them, but will eat them happily. But the same plant can keep sprouting again for about 10 seasons if it's not allowed to produce its seeds. If allowed to produce them, the plant will die off. So there's 2 other ways to get rid of it:
1 - Dig most of its root up to kill the plant.
2 - Let the plant produce its seeds and then cut away the flower/seed heads and pack them away for destruction.
my brother got second-degree burns last year from what he believes may have been a lemon.
Thank you, lemons, for teaching us about phytophotodermatitis so that I knew what this video was talking about.
As an ecological land manager, I really appreciate you highlighting this invasive species, and bringing the science to it. You could have scienced a little harder by including the term "allelopathic"... and a mention that wild parsnip (Pastinaca sativa), which is much more abundant in North America anyway, also causes phytophotodermatitis, would have been worthwhile.
