I just read your introduction, and it sounds like this program is perfect for you! Thanks for joining this blossoming online community. Your property sounds amazing.
I’m sorry to hear about the trouble that burdock causes you, but at least it makes for a tasty and helpful herbal medicine.
On Vancouver island, there are 2 types of burdock found, Arctium lappa, and Arctium minus. Both are medicinal/edible. If you’re able to confirm that the plant you have is indeed one of these species, and you feel confident that the land is free from contamination, then you can harvest and consume the roots.
If you’d like, you can upload a photo of it and I can try to assist with identification.
