The leaves can be cooked like spinach, the young shoots fried up or boild like green beans. Grandma used to make jelly from the flowers, and the tubers can be cooked like potatoes, or dried and ground into a flower substitute!
That being said... I cant stand it! (the plant not the food) its very hard to kill!
I don't mind it so much way over there but not any closer.. Good source of food in a pinch though!
Thanks for the comment! We did not have this issue up on Illinois. We are getting ready for it, only 500 to 600 feet away.... I should try some cooked....
