I have a group of weeds growing in the back of my yard. I've touched them twice and it hurt really bad for a long time. I thought it was a spider bite or something, so I finally looked up the plant's name, and its Stinging Nettles. I was ready to pull it all out until I read that some butterflies really like it.
I'm in zone 5. Should I leave it for the butterflies, but just put up a big warning sign haha........or should I pull them? Those little thorns really, really hurt!
