My advice is try nettle tea, harvest early in summer, week or 2 into june here in Canada. I put the nettles in pail of water and soak for a day or 12 hours? Then pour water in kettle and put some of nettles in with it boil and it's good. Other advice is you can eat thistle flowers when they're young, just spit out the covering. If theres a plant you dont like/invasive/worthless just rip it out.
