My whole backyard is full of this stuff and I'm trying to find out if its edible or has any medicinal value before i get rid of it. Also are there any ways i can get rid of it without using harmful chemicals?

Urtica chamaedryoides?

One year, I put on some welders gloves and picked a pot full... Cooked it up, and had an excellent broth.
I waited too long to harvest, and the leaves and stems were too tough to eat... they were discarded, but I totally want some more of that broth!

You may have waited too long...

to be on the safe side the plant should not be eaten after flowering.
