That’s another free-bee from Mother Nature! We have plenty of that ‘weed’ here, too.
Read a cute short piece the other day. A woman was asked by her neighbor if she would take Rhubarb off his hands - he had SO MUCH! She said yes, and he delivered bag after bag after bag...of BURDOCK! LOL!
When my Dad would visit he thought we were so lucky to have some burdock. He boiled the leaves, drained them, then battered and fried them. I passed.
