I live in Oklahoma. I neighbor has a trifoliate orange tree. Last year we had a record cold February. The temperature got below -10 degrees and the temps stayed below freezing for a month. His tree survived the winter with no visible damage. The fruits can be used to make a tea or to flavor other teas and beverages. It is slightly sweeter than a lemon. It is very fragrant. The fruits have many seeds in them, and the skin is fuzzy, kind of like a peach. I dug up some seedlings that had sprouted at the base of his tree. I'm planning to plant them in my yard when they are big enough.
What about Sea Buckthorn, here in denmark we call it then nordic citrus. Its a real pain to pick and normally you cut the branches throw them in the frezer with the berries on, and when its frozen solid you can knock the berries of and avoid all the thorns. Its an extremely healthy and potent fruit which can survive our frozen winters.
Hey here is my bit of knowledge, orange peel can be boiled in water and make soft and tasty then add sugar and keep cooking till the syrup is done and yeah icecream topping, cake decoration and they have a real good texture too.
For anybody struggling growing citrus in the north like me,I found If you do a heavy straw/grass clipping mulch around the base it can give you up to a 15 degree buffer. meaning if it's hardy to 15F it could potentially survive 0F
That defies basic thermodynamics: in cold weather the heat from the ground saves your tree. If you use mulch you block that heat source. As the previous commenter said you have to cover the tree with leaves. And I have done that with small trees. I have also used droplights, and passive heating, by putting a garbage can full of water inside a covered frame next to the tree. The water releases heat as it cools. The citrus must be "hardened off" for this to work. Frost blanket gets you about 6° F protection per layer. My small trees survived two nights 14° & 17° F with 30 hours below 25°F. with cover and passive water heating. Trees were tangerine-tangelo hybrids, fairchild, sunburst, and page and pink navel orange. Some of the top growth was lost on two trees but the fairchild promptly bloomed. Look for hardy Kat Mandarins, Karagi, and Changsha for tasty cold hardy fruit. Even these are only good for single night dips to about 18°F without additional protection. And ichang lemon is wonderful if you like terpentine flavored fruit.
@@leventebognar7635 I used pipe insulation (they look like pool noodles but have a slit to cover pipes) on the trunk, heavily mulched around the base and covered w frost cloth during a brief freeze in Texas. They survived! Others moved their citrus to a garage and they still died. I wonder if I just got lucky but I'm glad it worked!
I grow many varieties of citrus trees in my garden and in pots. Most of them are grafted on trifoliate orange or yuzu, which gives the scions cold hardiness. Cumquats and yuzu were traditionally used for the skin. Cumquat skin as medicine, and yuzu skin for all sorts of seafood cooking. My cumquat is a seedless variety with 20% sugar content inside, so I always eat it whole. I also have seedless yuzu, kabosu, and sudachi - they are all wonderful with Japanese cooking.
Thank you for this list!!! We are about to relocate to some place much colder and are grateful for this list. Please continue to share other cold weather edible plant lists. We really want to be able to grow some of our own foods for sustainability.
I found the Trifoliate Orange growing wild in a cow pasture in Salem, Virginia when I was a kid. When we moved to Florida I dug up a couple of seedlings to take with me but was never able to get it to fruit in Florida. I don't think it even bloomed down there. I'm living in southern Illinois now which has a very similar climate to Roanoke County area so I may try getting seeds or live plants for my back yard now that I finally know what its called. I never saw it get over 6 feet tall. It grows like a bramble. I always thought of it more like a wild lemon than an orange. Makes a decent lemonade.
I love kumquats. We grew them for years in Northern California. Additional feature is that if the flowers or fruit are lost from cold, drought or heat, it will re-bloom. Super productive. Makes super marmelade.
Kumquats are very underrated as a fruit. i like to eat them whole, skin and all. Glad to see that there are some citrus plants that can handle lower temps. Thank you for this list as it gives me more options to think about growing.
@@jennifervondeylen7362 Kumquats taste like a sour/tart orange. The inside of the skin is sweet, but the fruit is tart. When you eat the entire fruit, skin and all, it tastes sweet and slightly sour. It's nice.
Thank you for the info. Besides the citrus mentioned tolerance to frost, the trees adapt themselves to the environment (to some extent) and also to the particular place they are grown in is important. Ex, south side in the back of a wall (north hemisphere) gives the citrus species a good protection. I have a citrus tree (Citrus aurantium) that was already growing in a plot for over 20 yrs, that I bought and in that place there have been heavy frost (once each 10 to 20 years or so) of -12 ºC (10ºF) and that tree is standing there and produces lots of fruit. The fruit is sour but its juice with a more complex flavor than lime/lemon. I use the juice of that sour orange for: Guacamole, for a water + honey drink, for cooking some stews (peel and juice) etc... With the kumquat i do prepare a drink: the whole fruit +water+honey in the blender and then strain it, delicious with vitamin C.
I love how so many fruits with "Arctic" in their name don't even get hardy into the negatives. It was -28F here last week and I'm not even close to the arctic circle.
I have some Owari Satsuma and another satsuma grafted onto trifoliate. Apparently Trifoliate will actually add a few more degrees of cold tolerance since it goes dormant early… which stops growth and adds much more bark.
I also have Owari Satsumas on trifoliate rootstock. They've lived here in North Georgia for 8+ years now. Generally cold hardy citrus doesn't taste as good as those that are not, but in my opinion this is the best tasting fruit of all citrus.
@@Cristofre That is why I went with Owari. It is supposed to be amazing still... but the most hardy of the good tasting ones. I may get a Yuzu or something down the road. We shall see.
The best citrus that is still edible for zone 7 is Sudachi (Yuzu x Mandarin hybrid). I'm sure it can be even further improved if arctic frost satsuma is used for one its parent instead of some random not that hardy mandarin
in my opinion arctic frost satsuma is just branded to be super super cold hardy, which it really is not. more hardier are trifoliate hybrids, yuzus and some other pure varieties
I totally agree with you. Sudachi is by far the best of the ‘hardy’ citrus. That does well in chilly regions. There are very productive sudachi trees in the Portland, Oregon area.
Sadly I lost all my citrus trees to scale. It had gotten pretty bad. Had to let them go. But I'm not giving up. I love citrus trees and they're great for tea leaves.
indeed....scale is the major problem for us northerners.....I lost all my citrus hybrids to scale...all but one lemon grown from seed from a store bought lemon.
We're in zone 4/3, mostly 4 but in a microclimate and some maps show part of my property to be zone 3 and we definately have a temperature difference than just a half mile away. the coldest one you listed might make it if it would stay short enough for a greenhouse, but my orchard is not inside a greenhouse. We have hardy kiwi growing, so maybe someday a hardy citrus will be possible, in the meantime my berry bushes are a guarenteed harvest and if my fruiting trees want to cooperate (or if frost and bugs leave them alone), then that's something to celebrate. Yeah, something definately wrong with artic in a name and it can't handle below zero.
Liked the variety of plants you choose. I don't know a lot about how to use the internet so maybe my choices are limited. But I have always had great fondness for Logees they have been in business for well over 70 years and I remember fantasizing about the unusual tropical plants they had when I was a child. Please check into their site. I have a cold hardy kiwi I got from them that's done wonderful. The variety is 'Jenny' 💋🍀
Amazing! I would love to have one for my garden but i am still worring about the climate! I do live in Belgium and its very wet the winter here! What country do you live btw?
I live in western Oregon in zone 8b. The only citrus worth planting in the ground here is the yuzu, either the sudachi or ichandrin. Sudachi is more like a tart tangerine and unlike the ichandrin has very few seeds. The poncirus does well here too, but the fruit is subpar at best. The only one I would recommend for in ground unprotected in zone 8 is the yuzu. In zone 7 the yuzu will require a cover and some heat from Xmas lights to survive. I wouldn’t even bother with these uncovered in zone 6 or lower. Personally I wouldn’t put yuzu in the ground below some 8. If you are a zone 8 you can do all the other citrus in pots and bring them in and out of a greenhouse. I grow all sorts of sensitive citrus in the Portland, OR area and they are outside about 80% of the time in the winter. My yuzu fruit prolifically. But we rarely get below 20F and the Willamette Valley is hot in the summer which really helps the citrus sweeten. If anybody wants to watch videos of a guy who grows lots of citrus on Vancouver Island in Canada look up Bob Duncan’s video about growing yuzu on Vancouver Island. He has plenty of videos on UA-cam.
I have several hybrids that survived -12°F at 8 months of age. Their tops were beat up, but there were surviving stems. 1 of the survivors fruited this year and makes a decent drink when sweetened and diluted.
@@jonathanstephens7015 The trees are second generation hybrids between Ruby Blood Orange and trifoliate orange. A few dozen survived out of an initial population of 20,000 seedlings. The survivors have been further tested and several hundred have been propagated and planted outdoors. There's some variability among the selections regarding hardiness. The best ones show consistent hardiness, with 0 degrees not being lethal. Only one selection has fruited at present.
I guarantee you the zone 8 you live in isn’t in the Pacific Northwest. I also GUARANTEE you that a meyer lemon will eventually die back to the roots if grown unprotected in a zone 8. Eventually a zone 8 will have a harsh winter that will kill your sensitive citrus like meyer lemon, Bearss lime and navels. Even where I grew up in a zone 10 in Southern California we had a wickedly cold snap in the late 80’s that killed most of my family’s citrus trees. Believe me, I raise citrus for a living, and I know what can and cannot survive in zone 8. While it’s possible to baby along many citrus in zone 8, for the sensitive citrus that are well known commercially, you will eventually need some kind of cover when temps drop into the teens. I live in western Oregon now and grow loads of citrus, but they are all under an unheated covered patio with a polycarbonate roof. My citrus thrive and this is a zone 8b/9a transition region. The only citrus I can grow outside unprotected are sudachi, yuzu and trifoliate hybrids. I have a Carrizo and citramelo that survive year after year without protection. The meyer would get brutalized here without the cover over its head and the warmth from the walls heating the local growing area.
We are planning on putting those trifoliate oranges along our public facing areas of the homestead we are building, while it can be a bit aggressive its generally easier to manage than most thorny things. My understanding is they are a bitter orange variety , so not great for fresh eating , but they can be used for marmilade
I'm so excited for you! I love Yuzu trees! You won't be disappointed. Thank you so much for your continued support and always taking the time to watch the videos. It means so much to me. Happy growing!
Poncirus trifoliata is available in a number of cultivars. The contorted versions are called "Flying Dragon". There are a number of selections that have less offensive flavors, "Poncirus+" and "Swamp Lemon" are 2 such selections. There are many Citrus X Poncirus hybrids, with variable hardiness, as well as palatability.
Palatability? Not sold on that. Poncirus makes a great rootstock. I know a citrus breeder that first crossed commercial with poncirus in 1993 or so. They just are getting to reaonsable fruit now....
@@DrKevinFolta It all depends on what the definition of reasonable is. I quite enjoy certain qualities of each of these fruit. Perhaps not all are good for fresh eating. But the uses are there. With Yuzu and Flying Dragon I quite enjoy the taste. Palatability is in the eyes of the beholder. But I absolutely see what you're saying.
Thank you so much for such helpful information . Are you planning to put out a video on cold hardy flowers and herbs as well? It would be truly appreciated.
Absolutely. If you haven't already please hit that subscribe button to see our future content. Thank you so much for taking the time to watch. Happy growing!
The last tree you talked about the thorns. I had a grapefruit tree that I grew from seed that had 2 to 3 inch thorns that would cause a lot of pain is scratched by one.
Was the fruit nice that your grew from seed though? I have some I’m growing from seed atm and some have thorns and some don’t. I can’t wait to see what they turn into. I also have a couple of grafted lemon trees that fruit so I don’t mind waiting a few more years for the seedlings 🌱 to fruit.
Some advice for anyone growing citrus in climates with cool summers: Sour citrus such as kumquat, calamondin, lemons, yuzu and limes will ripen well even with summer temperatures below 70 F, whereas oranges, mandarins and grapefruit need warmer summers.
I'm right there with you. I love Kumquats. Thank you so much for taking the time to watch the video. It feels wonderful to have your support. Happy growing!!
The last plant on this list, Poncirus trifoliata is the cold hardiest one but at the same time even the juice is bitter, hence its called Bitterorange in German. Funny enough i just found a fruit sold on ebay which is labeled as Bitter free Poncitrus trifoliate hybrid #7 - Woodlanders, seller bought the plant back in 1994/95 and even uploaded a recipe from the Auction, apparently its very rare and even the seedlings turn out crazy, like variegated, bitter free, weird shapes and forms of the fruits and even the leafs are way bigger, im buying this fruit.
Yuzu ( although possibly a different variety) is the basis for traditional Japanese salad dressing. And ask for wafu(和風 - literally Japanese style) dressing at any restaurant in Japan ( even Denny's) and you will get a yuzu-based dressing. It is my favourite.
How would snow affect the cold hardyness of these plants? I live in the sierra nevada foothills in norcal and it doesn't get very cold in the winter, rarely below 25℉ most nights, but we do get a decent bit of very dense, heavy snow. Known as sierra cement, it freezes rock solid the night after it falls.
You're so lucky! I'm jealous of the weather you have out there. I appreciate you taking the time to watch the video. Your support means the world. Happy growing!
I’ve been pondering if I should try hardy citrus or not here in the Philly area. This video was helpful, especially with the taste info. Thank you for this. 🍊
Absolutely no problem. Thats exactly what I hope these videos will accomplish. I see no reason why you shouldn't give these a try. They are so much fun to grow. Thank you for taking the time to watch the video! Happy growing!
using acetone will help get rid of the sticky sap of Poncirus trifoliata. I have a tree, and my parents have a tree as well. NC near Raleigh, zone 7b. Both are producing dozens of fruits each season.
Yuzu died to the ground here in 7a after 6f but it grew back in the summer from the roots. It did survive The previous year to that after 11f with no trunk damage. Would benefit being covered if you will drop below 10f.
I grew a navel orange tree from a single seed I found in a store-bought fruit, it’s thorns are as big as those shown on the trifoliate! No flowering yet, 5 years on.
Same on my 8 year old seed grown lemon tree. If its in a pot it can take much longer than if its a seedling grown in the ground. Thanks for taking the time to watch the video! Happy growing!
Great information given in a short and to the point video. I collect citrus and have just reached 15. Qumquats are my favorite! You haven’t mentioned Limequats . Are they not cold hardy? Just subscribed and all the best. Thanks
Anything mixed with Kumquat is going to have a little added hardiness to it. But the total cold hardiness of a kumquat is not present in a hybrid tree.
Is it the root stock that is most critical to be hardy at lower temperatures? Just wondering if say, grafting an Arctic Blast satsuma onto a root stock of one that is even hardier will give it an even larger range.
The rootstock does somewhat add hardiness to the tree. But ultimately it will be the scion that produces the fruit you desire, and a tree is really only as cold hardy as the scion. Typically the rootstock used on citrus trees is a flying dragon, which is used mainly for its dwarfing habit. It just helps keep the trees size in check. If ever a grafted trees top growth is killed to the ground and new growth emerges from the roots in spring, this will not be the fruit you planted but the rootstock growing out.
Zne 6b. I planted a 8" seedling n in june and it did not survive the winter. Mybe a much thicker mulching. have just planted a 3' mini tree and it seems tobe thriing. I will mulch it and hope for flowers in the next spring.
I recently moved to Oregon and miss my Cali citrus. This winter, so far, it has gotten down to -4°F, however, last summer we spent many days over 100°F. Are these going to have issues with the extreme heat of summer?
It really shouldn't be an issue. 100 F isn't as uncommon of a temperature as you might think. But if it becomes necessary you can always buy a little shade cloth and only use it on those crazy hot days.
A woman gave me some fruits of a tree that was as big as a house! That winter it was killed by very cold temps. The fruits she called a lemon. Not like American lemons from the store. They felt slightly fuzzy. Maybe 3 inches across. Not bumpy like the uzzu. With a rather unusual taste. I never could decide that I actually liked it, but was trying to develop a taste for it! She said she got it from a farmers market and did not know the type. She thought it was grafted on a root stock. Last year she gave me a young tree, but the leaves do not look like the other tree. It looks like the trifolium. Any ideas out there?
Just discovered your channel and loving it, keep up the great work. Just visited your website hoping to purchase some items you featured on your site such as long black grape, hardy kiwi will you eventually have them for sale?
I'm in Minnesota and don't think any of those would fly here, but good presentation, have you done a presentation on Musa Basjoo banana? If you are going to be around thorny plants nail clippers take the tip off.
Even when that's included, it doesn't necessarily help since some things cannot be shipped across state lines and nothing live can be shipped across international borders.
Trifoliate, I always wondered what that was. No body I asked seemed to know. They grow wild in central Ms. And yes the thorns are murder. They will puncture tires with ease. Fixed many a John Deer tractor tire (farm tractors). Flat due to a thorn from one of them trees.
it's rare we get so cold, but last year it got down to 22F, then 23F this year. The calamondin froze back but tried to bloom. Too much smoke coming over from Cali forest fires, tho. Only 1 crop from the kumquat this year, not 3 and the tangerines were slamm with thick skins. AKA too much nitrogen. Funny thing, tho the chili in the pot out front (south side) froze back, chiltepin in the barden only got burned.
More videos coming in the future, so if you haven't already hit that subscribe button for more. Thank you so much for watching the video! Happy growing!
This might be a little random but you should grow black sapote, it’s a delicious tropical fruit that kinda taste like chocolate pudding and is really sweet!
I had the trifoliate orange for about 20- 25 years. It had an 8" base and about 15' tall. It was cold hardy to below zero one winter. As stated the thorns are anti-personnel type. I just cut it down this fall. The one I had, the fruit was very bitter, the skin was thick, the seeds were large. It took a lot of fruits to get any quantity of juice. It looks likes like I will be fighting the invasive plants sprouting up all around. Maybe there is a better variety than I had . . .
Sounds like it might be good for using as zest or candied skins. There are many citrus that are grown more as a spice than as a juice. Or possibly cooked, for candies or jams.
Absolutely. There are many uses for different citrus trees besides fresh eating. With that being said I have certainly seen Trifoliate Orange varieties that are juicier than others. It sounds like you had quite the tree on your hands. Very cool. Thank you so much for taking the time to watch the video. It means so much. Happy growing!
I have it growing in my yard in 7a, easily survived our snap cold last year of days below zero. The Zest of it is used to make orange marmalade. Definitely a unique home made item to give out at Christmas.
I’m growing Poncirus trifoliata in z6b Massachusetts for 15+/- years and survived -13F following by -6F the next night. Very minimal damage, just a few branch tips were damaged. It self seeds in my garden.
Where can I get the kumquat tree to grow in colder climate Arizona.. Also Ive been looking for the trifolate root stock citrus varieties, but they state that they cannot sell to Arizona for some reason..
I've been trialling Poncirus trifolata as have others in Nova Scotia. All trials in Halifax have died, some specimens in the Annapolis Valley put on new growth and then die back that growth every year. We are zone 6a and b
@@off-labelbotanist5355 Have you trialed flying dragon? It should have no problem surviving zone 6 temperatures. I'm glad to hear of this going on! Keep me posted!
I have citrus trees, which the graft died. The rootstock survived freezing days, which wasn't regular more than 5 years ago. I'm assuming that this rootstock is trifoliate. Bitter orange seeds are also cold hardy. These aren't sweet like lemon. A lot of full size citrus trees died in my city, which shows this amount of freezing wasn't common years ago. It always warmed up during the day, but now we're getting more irregular weather.
I tried growing flying dragon from seed a few years ago. They did well indoors and were a beautiful plant, but I live in Michigan. They did not even survive our autumn.
It can somewhat, but not enough to make a tremendous difference. Usually flying dragon rootstocks are utilized for their ability to give large crops while giving the scion a dwarfing habit.
@Plant Fanatics Any tips for dealing with spider mites? When I brought my citrus inside for the winter, the mites killed them before I knew it was happening.
Make a mixture of Neem Oil and Dawn Dish Soap in a spray bottle and spray it all over your plant. Repeat this process for 7 days and they will all be gone. I always spray this mixture on my plants before moving them back into the greenhouse. Happy growing!
OMG this made my day. My heart is pounding like crazy, because there is actually a chance for me to grow some citrus in my cold climate!!!!!! THANK YOU ❤️👍🏻❤️

I keep my citrus plants inside for my -40F winters. I don’t think they should call something “Arctic” if it cant handle below 0F temps.
Trifoliate orange can survive minus degrees
Same it gave me good vibes then turns out it’s not as Hardy :( I live in zone 7 but we get like zone 5 drops
No kidding, I live in zone 4 and am always looking for cold hardy plants
Exactly. Outside of Chicago is hardly arctic. But we just had -18°f for a week...

The thorns on that Trifoliate Orange remind me of an English Blackthorn.... the pokeyness is real. 😁😅😅
Sadly I lost all my citrus trees to scale. It had gotten pretty bad. Had to let them go. But I'm not giving up. I love citrus trees and they're great for tea leaves.
indeed....scale is the major problem for us northerners.....I lost all my citrus hybrids to scale...all but one lemon grown from seed from a store bought lemon.
Well thank you now I need to get some of these. My wife will be very happy.
Happy wife happy life. You're a smart man. Happy growing!
@@PlantFanatics Let me re fraise it "very happy".
We're in zone 4/3, mostly 4 but in a microclimate and some maps show part of my property to be zone 3 and we definately have a temperature difference than just a half mile away. the coldest one you listed might make it if it would stay short enough for a greenhouse, but my orchard is not inside a greenhouse. We have hardy kiwi growing, so maybe someday a hardy citrus will be possible, in the meantime my berry bushes are a guarenteed harvest and if my fruiting trees want to cooperate (or if frost and bugs leave them alone), then that's something to celebrate. Yeah, something definately wrong with artic in a name and it can't handle below zero.
Citrumelo goes way lower, I have one in my garden and last winter it survied (packed in, but without heating) a week with -12c during the night!
I recommend spicebush in zone 4; lindera benzoin. Its berries are citrusy and peppery
Thanks! I might look into that.
Trifoliate is invasive in some states including North Carolina. Double check before growing.
Where can you find Trifoliate in the wild in NC..?
I have an arctic frost satsuma, the fruit is delicious. Highly recommend.
Thanks for the comment!
Liked the variety of plants you choose. I don't know a lot about how to use the internet so maybe my choices are limited. But I have always had great fondness for Logees they have been in business for well over 70 years and I remember fantasizing about the unusual tropical plants they had when I was a child. Please check into their site. I have a cold hardy kiwi I got from them that's done wonderful. The variety is 'Jenny' 💋🍀
I love Logees! I’ve bought many a plant from them! Thanks for the great comment!!
The idea of growing citrus in the winter🔥
Really love the video. My yuzu citrus in the ground is doing well. -7 the other day. It still looks great.
Amazing! I would love to have one for my garden but i am still worring about the climate! I do live in Belgium and its very wet the winter here! What country do you live btw?
@@lucian.cojocaru8731 In rainy New Jersey usa
To pick fruit on the inside of the tree, use one of those 'grabbers' to reach "out of reach" items.
I live in western Oregon in zone 8b. The only citrus worth planting in the ground here is the yuzu, either the sudachi or ichandrin. Sudachi is more like a tart tangerine and unlike the ichandrin has very few seeds. The poncirus does well here too, but the fruit is subpar at best. The only one I would recommend for in ground unprotected in zone 8 is the yuzu. In zone 7 the yuzu will require a cover and some heat from Xmas lights to survive. I wouldn’t even bother with these uncovered in zone 6 or lower. Personally I wouldn’t put yuzu in the ground below some 8. If you are a zone 8 you can do all the other citrus in pots and bring them in and out of a greenhouse. I grow all sorts of sensitive citrus in the Portland, OR area and they are outside about 80% of the time in the winter. My yuzu fruit prolifically. But we rarely get below 20F and the Willamette Valley is hot in the summer which really helps the citrus sweeten. If anybody wants to watch videos of a guy who grows lots of citrus on Vancouver Island in Canada look up Bob Duncan’s video about growing yuzu on Vancouver Island. He has plenty of videos on UA-cam.
I have several hybrids that survived -12°F at 8 months of age. Their tops were beat up, but there were surviving stems. 1 of the survivors fruited this year and makes a decent drink when sweetened and diluted.
What varieties did you hybridize? I’ve never heard of any citrus hybrids hardier than 0. And even that is very iffy.
@@jonathanstephens7015 The trees are second generation hybrids between Ruby Blood Orange and trifoliate orange. A few dozen survived out of an initial population of 20,000 seedlings.
The survivors have been further tested and several hundred have been propagated and planted outdoors. There's some variability among the selections regarding hardiness. The best ones show consistent hardiness, with 0 degrees not being lethal.
Only one selection has fruited at present.
@@jonathanstephens7015 Wow, I've even had a Meyer lemon get through our zone 8 winter. Your recommendations are too limiting.
I guarantee you the zone 8 you live in isn’t in the Pacific Northwest. I also GUARANTEE you that a meyer lemon will eventually die back to the roots if grown unprotected in a zone 8. Eventually a zone 8 will have a harsh winter that will kill your sensitive citrus like meyer lemon, Bearss lime and navels. Even where I grew up in a zone 10 in Southern California we had a wickedly cold snap in the late 80’s that killed most of my family’s citrus trees. Believe me, I raise citrus for a living, and I know what can and cannot survive in zone 8. While it’s possible to baby along many citrus in zone 8, for the sensitive citrus that are well known commercially, you will eventually need some kind of cover when temps drop into the teens. I live in western Oregon now and grow loads of citrus, but they are all under an unheated covered patio with a polycarbonate roof. My citrus thrive and this is a zone 8b/9a transition region. The only citrus I can grow outside unprotected are sudachi, yuzu and trifoliate hybrids. I have a Carrizo and citramelo that survive year after year without protection. The meyer would get brutalized here without the cover over its head and the warmth from the walls heating the local growing area.
We are planning on putting those trifoliate oranges along our public facing areas of the homestead we are building, while it can be a bit aggressive its generally easier to manage than most thorny things. My understanding is they are a bitter orange variety , so not great for fresh eating , but they can be used for marmilade
Thanks, this is great! I have a little Yuzu that will stay in a pot until it's large enough to go in ground. Cant wait.
I'm so excited for you! I love Yuzu trees! You won't be disappointed. Thank you so much for your continued support and always taking the time to watch the videos. It means so much to me. Happy growing!
Poncirus trifoliata is available in a number of cultivars. The contorted versions are called "Flying Dragon". There are a number of selections that have less offensive flavors, "Poncirus+" and "Swamp Lemon" are 2 such selections. There are many Citrus X Poncirus hybrids, with variable hardiness, as well as palatability.
Thanks for the info. Thanks for taking the time to watch. Happy Growing!
Palatability? Not sold on that. Poncirus makes a great rootstock. I know a citrus breeder that first crossed commercial with poncirus in 1993 or so. They just are getting to reaonsable fruit now....
@@DrKevinFolta It all depends on what the definition of reasonable is. I quite enjoy certain qualities of each of these fruit. Perhaps not all are good for fresh eating. But the uses are there. With Yuzu and Flying Dragon I quite enjoy the taste. Palatability is in the eyes of the beholder. But I absolutely see what you're saying.
@@DrKevinFolta It makes the best pie with its juice & sweetned condensed milk. If you eat sweets, you should try it!
Are there any poncirus without the thorns? That's the offensive part for me. I was just casually looking at one and yet somehow got jabbed.
I have a pair of boots that still have numerous trifoliate orange thorns imbedded in the soles from pruning. Those thorns are seriously wicked.
You're not kidding! I always tell people they are no joke.
Thank you so much for such helpful information . Are you planning to put out a video on cold hardy flowers and herbs as well? It would be truly appreciated.
Absolutely. If you haven't already please hit that subscribe button to see our future content. Thank you so much for taking the time to watch. Happy growing!
The last tree you talked about the thorns. I had a grapefruit tree that I grew from seed that had 2 to 3 inch thorns that would cause a lot of pain is scratched by one.
Yes, the thorns on these trees are no joke at all! Happy growing!
Was the fruit nice that your grew from seed though? I have some I’m growing from seed atm and some have thorns and some don’t. I can’t wait to see what they turn into. I also have a couple of grafted lemon trees that fruit so I don’t mind waiting a few more years for the seedlings 🌱 to fruit.
@@NMW80 the grapefruit was good. They seemed to produce year around. This was in San Jose, California.
Finally a cold hardy video with actual plants that can take the cold.
I talk about all these and plus many more hardy citrus on my channel.
Some advice for anyone growing citrus in climates with cool summers: Sour citrus such as kumquat, calamondin, lemons, yuzu and limes will ripen well even with summer temperatures below 70 F, whereas oranges, mandarins and grapefruit need warmer summers.
Citrus is my favorite! Kumquat is the best! I am going to try to grow kumquat.
I'm right there with you. I love Kumquats. Thank you so much for taking the time to watch the video. It feels wonderful to have your support. Happy growing!!
@@PlantFanatics Do you know of any satsuma types that are even more cold hardy than the average satsuma?
The last plant on this list, Poncirus trifoliata is the cold hardiest one but at the same time even the juice is bitter, hence its called Bitterorange in German. Funny enough i just found a fruit sold on ebay which is labeled as Bitter free Poncitrus trifoliate hybrid #7 - Woodlanders, seller bought the plant back in 1994/95 and even uploaded a recipe from the Auction, apparently its very rare and even the seedlings turn out crazy, like variegated, bitter free, weird shapes and forms of the fruits and even the leafs are way bigger, im buying this fruit.
Yuzu ( although possibly a different variety) is the basis for traditional Japanese salad dressing. And ask for wafu(和風 - literally Japanese style) dressing at any restaurant in Japan ( even Denny's) and you will get a yuzu-based dressing. It is my favourite.
Love it! Thanks for sharing!
Great info!
Thanks for the video! I have been looking for a list of fruit trees that I can grow here in Newfoundland and this list was great knowledge to have.
Thanks so much for watching. Happy growing!
Trifoliate orange sounds as pleasant as the honey locust
No reason to ever buy one. They are used for rootstock. If a freeze dies your mandarin to the ground it will probably regrow as a trifoliate.
It tastes awful! It's inedible...
How would snow affect the cold hardyness of these plants? I live in the sierra nevada foothills in norcal and it doesn't get very cold in the winter, rarely below 25℉ most nights, but we do get a decent bit of very dense, heavy snow. Known as sierra cement, it freezes rock solid the night after it falls.
Great content! In Southern California, I do not need to worry about this cold but I definitely want to understand the “big picture”. Thanks!
You're so lucky! I'm jealous of the weather you have out there. I appreciate you taking the time to watch the video. Your support means the world. Happy growing!
Yes, I live in the Naval capital of Cali, also I have 2 great mandarin trees, only problem is that they seem to be alternate year bearers
@@eleanorroberts1886 Oh really? Thats pretty crazy to hear!
Thank you so much for this video!
Thanks for watching it!
I’ve been pondering if I should try hardy citrus or not here in the Philly area. This video was helpful, especially with the taste info. Thank you for this. 🍊
Absolutely no problem. Thats exactly what I hope these videos will accomplish. I see no reason why you shouldn't give these a try. They are so much fun to grow. Thank you for taking the time to watch the video! Happy growing!
In large containers, protected by a nice tall greenhouse .
Why not. The leaves of citrus trees by the way make an awesome herbal tea.
@@heidimisfeldt5685 Awesome thank you!
Thanks so much for Sweet Fruity Video. Need resource's to order from. Local nursery does not have any of these!
I would just do a quick Google search and/or read forums. Some plants are more about who you know honestly
using acetone will help get rid of the sticky sap of Poncirus trifoliata. I have a tree, and my parents have a tree as well. NC near Raleigh, zone 7b. Both are producing dozens of fruits each season.
Thanks for the great tip! I'll be sure to keep it in mind next time the sap gets everywhere. Happy growing!
The One Green World nursery sells a cold-hardy citrus bundle. It has flying dragon (the one with giant thorns), Sudachi Yuzu, and Yuzu Ichandrin.
Yuzu died to the ground here in 7a after 6f but it grew back in the summer from the roots. It did survive The previous year to that after 11f with no trunk damage. Would benefit being covered if you will drop below 10f.
The Trifoliate Orange tree has thorns like a Crab Apple tree. Very long and stiff thorns. They will easily pierce the skin
Yes they will. Pruning is very important. Most people don’t, however.
Seems Seattle is a zone 8. I might have to try out that cuties one. Hmm...
I grew a navel orange tree from a single seed I found in a store-bought fruit, it’s thorns are as big as those shown on the trifoliate! No flowering yet, 5 years on.
Same on my 8 year old seed grown lemon tree. If its in a pot it can take much longer than if its a seedling grown in the ground. Thanks for taking the time to watch the video! Happy growing!
Then it wasn’t a navel orange
@@romulushill9952 True, Navel Oranges are a seedless variety.
@@PlantFanatics
Sometimes you find the odd sèed, in seedless fruit.
How do they accomplish anything seedless??
... sounds so unnatural to me...
@@heidimisfeldt5685 They find 2 varieties that, when crossed, produce a 'seedless' offspring. Then they reproduce it via cloning, or cuttings.
I have the orange frost, owari and brown select satsuma
Very informative. Please keep up the good work.
Thank you so much for the kind words. It means the world. Happy growing!
Any recommendations for citrus fruit that will ripen in cool maritime summers?
Hold up but eating the lemon straight up is the best part 😋🥲.
Very impressive, I'm not familiar with any of them. lol Thank you!
Thank you for taking the time to watch the video! Happy growing!
Thanks for your information
Skins make good candies and jellies
this is fantastic 👍 I have small citrus started
It was -15 degrees here in Maine yesterday. Any planting tips for me ??
Poncirus may be able to withstand that temperature for limited hours.
Heavy heavy mulch. Number one tip
Great information given in a short and to the point video. I collect citrus and have just reached 15. Qumquats are my favorite! You haven’t mentioned Limequats . Are they not cold hardy? Just subscribed and all the best. Thanks
Anything mixed with Kumquat is going to have a little added hardiness to it. But the total cold hardiness of a kumquat is not present in a hybrid tree.
Can any of these take the Heat as well ? I'm in the California Mojave desert. We can go up to 120 ° d, and down to 13° in winter.
The only way to know for sure is to try it. I think it’ll take more input from you to make sure they are healthy though
Is it the root stock that is most critical to be hardy at lower temperatures? Just wondering if say, grafting an Arctic Blast satsuma onto a root stock of one that is even hardier will give it an even larger range.
The rootstock does somewhat add hardiness to the tree. But ultimately it will be the scion that produces the fruit you desire, and a tree is really only as cold hardy as the scion. Typically the rootstock used on citrus trees is a flying dragon, which is used mainly for its dwarfing habit. It just helps keep the trees size in check. If ever a grafted trees top growth is killed to the ground and new growth emerges from the roots in spring, this will not be the fruit you planted but the rootstock growing out.
@@PlantFanatics Oh, interesting! Thanks so much for all of the information!
Thanks for feeding my addiction!
Zne 6b. I planted a 8" seedling n in june and it did not survive the winter. Mybe a much thicker mulching. have just planted a 3' mini tree and it seems tobe thriing. I will mulch it and hope for flowers in the next spring.
I recently moved to Oregon and miss my Cali citrus. This winter, so far, it has gotten down to -4°F, however, last summer we spent many days over 100°F. Are these going to have issues with the extreme heat of summer?
It really shouldn't be an issue. 100 F isn't as uncommon of a temperature as you might think. But if it becomes necessary you can always buy a little shade cloth and only use it on those crazy hot days.
@@PlantFanatics Oh good! I'm definitely going to try one!
A woman gave me some fruits of a tree that was as big as a house! That winter it was killed by very cold temps. The fruits she called a lemon. Not like American lemons from the store. They felt slightly fuzzy. Maybe 3 inches across. Not bumpy like the uzzu. With a rather unusual taste. I never could decide that I actually liked it, but was trying to develop a taste for it! She said she got it from a farmers market and did not know the type. She thought it was grafted on a root stock. Last year she gave me a young tree, but the leaves do not look like the other tree. It looks like the trifolium. Any ideas out there?
I had no idea it was possible to grow any citrus north of Florida. Thank you!
Thanks for watching the video!
I'm in zone 8a They have satsuma orange orchards here and I'm in AL!
They grow a lot of citrus in Georgia.
great list! thanks!
Awesome! Got to start sone of these for a greenhouse!
Just discovered your channel and loving it, keep up the great work. Just visited your website hoping to purchase some items you featured on your site such as long black grape, hardy kiwi will you eventually have them for sale?
I'm in Minnesota and don't think any of those would fly here, but good presentation, have you done a presentation on Musa Basjoo banana?
If you are going to be around thorny plants nail clippers take the tip off.
So interesting! Question: I’ve always believed that the tree can withstand the cold but not the fruit. Is this correct?
In most cases, you are correct. It all depends on what type of tree it is.
A list in the comments or video description would be helpful for reference in obtaining these trees
Even when that's included, it doesn't necessarily help since some things cannot be shipped across state lines and nothing live can be shipped across international borders.
Trifoliate, I always wondered what that was. No body I asked seemed to know. They grow wild in central Ms. And yes the thorns are murder. They will puncture tires with ease. Fixed many a John Deer tractor tire (farm tractors). Flat due to a thorn from one of them trees.
They are the real deal thorns, no doubt!
How hot does it need to be to get good fruit?
it's rare we get so cold, but last year it got down to 22F, then 23F this year. The calamondin froze back but tried to bloom. Too much smoke coming over from Cali forest fires, tho. Only 1 crop from the kumquat this year, not 3 and the tangerines were slamm with thick skins. AKA too much nitrogen. Funny thing, tho the chili in the pot out front (south side) froze back, chiltepin in the barden only got burned.
Satsuma ; SATSOOMA .
Are these plants good for zone 7a/b
The information was very helpful... I'd like to know about pomegranites too
More videos coming in the future, so if you haven't already hit that subscribe button for more. Thank you so much for watching the video! Happy growing!
Do you have links to nurseries selling these varieties? Particularly the artic frost Satsuma?
Thank you so much
Just subbed its like you have read my mind thanks from soon to be free france
Great video!
Your channel moto should be “thanks for pruning in!”
This might be a little random but you should grow black sapote, it’s a delicious tropical fruit that kinda taste like chocolate pudding and is really sweet!
haha, I only have a Sapote tree that I grew from seed. Its about 3 years old now. Do you grow the tree?
sapote is amazing!
I had the trifoliate orange for about 20- 25 years. It had an 8" base and about 15' tall. It was cold hardy to below zero one winter. As stated the thorns are anti-personnel type. I just cut it down this fall. The one I had, the fruit was very bitter, the skin was thick, the seeds were large. It took a lot of fruits to get any quantity of juice. It looks likes like I will be fighting the invasive plants sprouting up all around. Maybe there is a better variety than I had . . .
Sounds like it might be good for using as zest or candied skins. There are many citrus that are grown more as a spice than as a juice. Or possibly cooked, for candies or jams.
Absolutely. There are many uses for different citrus trees besides fresh eating. With that being said I have certainly seen Trifoliate Orange varieties that are juicier than others. It sounds like you had quite the tree on your hands. Very cool. Thank you so much for taking the time to watch the video. It means so much. Happy growing!
I have it growing in my yard in 7a, easily survived our snap cold last year of days below zero. The Zest of it is used to make orange marmalade. Definitely a unique home made item to give out at Christmas.
I’m growing Poncirus trifoliata in z6b Massachusetts for 15+/- years and survived -13F following by -6F the next night. Very minimal damage, just a few branch tips were damaged. It self seeds in my garden.
Where can I get the kumquat tree to grow in colder climate Arizona.. Also Ive been looking for the trifolate root stock citrus varieties, but they state that they cannot sell to Arizona for some reason..
I've been trialling Poncirus trifolata as have others in Nova Scotia. All trials in Halifax have died, some specimens in the Annapolis Valley put on new growth and then die back that growth every year. We are zone 6a and b
We hope to continue trials
@@off-labelbotanist5355 Have you trialed flying dragon? It should have no problem surviving zone 6 temperatures. I'm glad to hear of this going on! Keep me posted!
I've seen established plants grown successfully in coastal Connecticut, which is roughly the same growing zone, apparently without any special care.
Central Texas:. 20° 3 nights in a row!!!!
I have citrus trees, which the graft died. The rootstock survived freezing days, which wasn't regular more than 5 years ago. I'm assuming that this rootstock is trifoliate. Bitter orange seeds are also cold hardy. These aren't sweet like lemon.
A lot of full size citrus trees died in my city, which shows this amount of freezing wasn't common years ago. It always warmed up during the day, but now we're getting more irregular weather.
I love calamansi limes. Will they grow in northern South Carolina?
I tried growing flying dragon from seed a few years ago. They did well indoors and were a beautiful plant, but I live in Michigan. They did not even survive our autumn.
What plant hardiness zone are you in?
The poncirus I planted in erly June has doubled in size 12 instead of 6 inches..
When grafting does the cold hardiness of the rootstock transfer to the graft?
It can somewhat, but not enough to make a tremendous difference. Usually flying dragon rootstocks are utilized for their ability to give large crops while giving the scion a dwarfing habit.
@Plant Fanatics Any tips for dealing with spider mites? When I brought my citrus inside for the winter, the mites killed them before I knew it was happening.
Make a mixture of Neem Oil and Dawn Dish Soap in a spray bottle and spray it all over your plant. Repeat this process for 7 days and they will all be gone. I always spray this mixture on my plants before moving them back into the greenhouse. Happy growing!
@@PlantFanatics Thanks! This is very helpful!
Great list! Thank you. I moved from a zone 10 to a zone 5. I miss citrus!
OMG this made my day. My heart is pounding like crazy, because there is actually a chance for me to grow some citrus in my cold climate!!!!!! THANK YOU ❤️👍🏻❤️
Haha I’m so glad!
