There is a weed identification guide put out by UC Davis. I'll look for the link if you want it. That is where I identified our common knotweed. It spreads out like a thick carpet. I kind of like it, and our goats love it.
Yes, Shella, I would love to have the link. Thank you! My thoughts when i have discovered these plants were to find out if maybe i had any medicinal plants in my yard or the very near by woods, but i guess none of the plants i posted are. Really wish i could discover some comfrey somewhere! Thank you everyone for your help on here!
