I HATE Perilla! I was just pulling a patch of 4 feeters yesterday. I've tried to stay on top of it and pull it when it is smaller because it can be tougher to pull out when it is 3 to 4 feet tall, especially if the ground is dry, but somehow one area got away from me and exploded. I have also found that effectively timing weed wacking can be difficult because it can keep coming back and blooming later than expected and it may also flower lower to the ground which can be harder to see. I've even found it flowering after herbicide application so I mostly try to pull it as soon as I spot it. As always your videos rock!
Thank you! Timing is everything when it comes to controlling invasives. Herbicide works best when perilla is smaller and actively growing but it can be sprayed anytime before it flowers. Once it is flowering it will set seed before the herbicide can do its job. If you weed whack it just as the buds are about to open it is usually the end for that plant, but it is tough to get that timing right all of the time. Between stiltgrass and perilla I have all I can handle at our place - and we have a bunch of other invasives too!
The perilla growing invasively across the eastern US is not in the same class as the varieties grown for cooking greens and oil. It has lost most of the culinary qualities.
That horrible stuff is EVERYWHERE around here. Thank you for making this video! I do have a couple of questions though. You mention in your video on stilt grass that it can be composted. Can you safely compost Perilla? And I've always been told that the plant is more toxic when it's wilted or wilting (for example when pulled, or mowed, or even suffering from a drought). Do you know if that's true?
I have not heard that about wilted perilla, just that the flowers and seeds contain the highest ketone levels. There are plants that do become more toxic when wilted, like wild black cherry leaves. I am no0t sure about composting perilla. I haven't seen anything saying it shouldn't be. I wouldn't compost it if it is flowering as it may still set seed in the compost pile if it doesn't heat up enough.
@@BackyardEcology Thank you. :) And please keep these great videos coming. I always learn something new from the information that you and Shannon post!
Oh! We have this everywhere in west Tennessee. In one area it’s 4 feet tall. We tried to clear the area using the goats and they wouldn’t eat it! Good thing I guess. Wow.
It does work over time, if there is much of a seed bank it takes a few years to work through it. I am assuming your are referring to using herbicide - stiltgrass can have explosive growth response to prescribed fire if it is not timed precisely.
Believe this must be the mint taking over the top of Table Rock mt, in SC. Great swaths of it growing at least three feet tall. This is a great pity as mountain top ecosystems are special often homes to unique flora.
Virginia copperleaf may look superficially like perilla when it is young, but the mature plants are quite different. Virginia copperleaf has a much narrower leaf, less pronounced teeth on the leaf edges, and the leaves have an alternate arrangement on the stem. Another copperleaf species, hophornbeam copperleaf, Acalypha osteryifolia, looks much more like perilla but also has an alternate leaf arrangement. The Acalypha species do not have a minty smell when crushed.
@@BackyardEcology Thanks, I have tons of copperleaf growing in my yard, it makes a nice ground cover. I used an app to tell me what I was dealing with. These apps are very useful, especially for rookies like me.
@@joanfrellburg4901 Plant ID apps are useful, but be aware that they sometimes give wrong IDs, and sometimes they are way off. They are getting better but always confirm the ID given by a point and shoot ID app with another source.
@@BackyardEcology Yes good point. I noticed that using a few apps is better than just one. Generally, if in doubt I let it grow until I'm sure it's a non native or invasive or undesirable plant before snipping it or removing it. The birds are doing such a great job of planting stuff, I really didn't need to buy seeds but I'm still doing it anyway !
Just saw one of these attractive looking plants for sale at a local small grocers at $1.⁹⁹. Looked really nice, was going to buy it, because I'd never seen it before & then decided to Google. Good thing this store put the name of the plant on the pot - close call & thanks for the info, much appreciated!
It is also toxic to humans. Too bad you didn't mention it. I have known and eaten it as I have been to the Orient a couple of times. The species of Perilla are the same in the US and Asia, regardless which species we are referencing. I have never questioned it until hearing you say it is toxic to livestock... soo I Googled several questions.
Toxicity to humans of the perilla growing wild in North America is debated. Some sources say it is toxic, others say it is safe. I know people who eat it. It is so highly toxic to ruminants because of the way they digest food - they metabolize the perilla ketones in their rumen into a more toxic form that causes lung damage. Since we don't digest food in the same way perilla doesn't have the same effect on humans at normally consumed levels. If enough of it is eaten it can be toxic to humans regardless of where it grows.
Perilla doesn't seem to do well in the more northern states. It is found in many of them, but it is very spotty. In the southeast the stuff is everywhere.
@@BackyardEcology I’ll bet temp and soil PH have something to do with it. It reminds me of stinging nettle. I leave a few patches until August so the admiral butterfly larvae get a chance to mature. Then I pull it.
@@davehendricks4824 It does resemble many of the nettle species. The nettles are easy to spot as they flower from the leaf axils and not the tips of the branches. There is a big patch of nettles next to our barn which I am happy about simply because they are not perilla!
@@davehendricks4824 The perilla or the nettles? I know both can be eaten (although I would stick to strictly culinary varieties of perilla as most of what is growing invasively has high ketone levels).
Here in San Jose, Ca. Asian markets sell perilla leaves for one to two dollars for a 10 leaf bundle. They are considered a delicacy and are very expensive.
That is a culinary variety of the plant. The ones found growing in the wild as an introduced invasive have lost much of those qualities and are quite toxic to livestock.
@@BackyardEcology Too bad they lost those qualities. I actively plant these in my garden as an herb and they are so special and delicious. I was thinking how fortunate you are to have them growing wild but i guess these ones are not tasty.
@@flynnk70 Not only are they not great to eat, perilla is a super aggressive invasive plant that can overtake native plant communities. It is also highly toxic to livestock and is a huge problem in pastures in the southeast.

The best part starts at 4:15! Don’t miss it
And perilla leaves and seeds are edible. The seeds are pressed for egamo oil as well. It has herbal properties in spite of being toxic to ruminents.

Great video and educational

@@mayfly1963 You are welcome! There are a lot of new things in the works for Backyard Ecology! Stay tuned for announcements in the coming months.

It is bad in TN. Livestock generally won't touch it unless there is nothing else to eat, but when they do it can be devastating to them.
does it have a thorn anywhere on it?
No, it does not have thorns.
Burning back works really well to rid of it and the grasses.
It does work over time, if there is much of a seed bank it takes a few years to work through it. I am assuming your are referring to using herbicide - stiltgrass can have explosive growth response to prescribed fire if it is not timed precisely.
Excellent information. I will be pulling this new garden invader immediately!
Thanks! Perilla is easy to control by pulling them up.

Could be. It is a huge problem across the southeast.
This looks similar to Virginia Copperleaf ( Acalypha Virginica ) which is a native plant. Be sure to identify this plant correctly.
Virginia copperleaf may look superficially like perilla when it is young, but the mature plants are quite different. Virginia copperleaf has a much narrower leaf, less pronounced teeth on the leaf edges, and the leaves have an alternate arrangement on the stem.

We have a plethora of perilla. I have eradicated it from my riding arena by pulling it by the roots, but we have too much of the evil stuff.
It is everywhere in the southeast! I pull, chop, mow, and even spray some areas and it is never ending, along with the stiltgrass...
Funny thing my goats are smart enough to leave it alone :skull
Livestock won't touch it until it is the only green thing left. Drought conditions are when most poisonings occur.
It is also toxic to humans. Too bad you didn't mention it. I have known and eaten it as I have been to the Orient a couple of times.

God I hate this plant. Growing up to 4-5 feet tall in Tennessee.
I've seen some super healthy specimens in the mid-south. It is the biggest herbaceous invasive problem on our farm in KY.
