The perimeters of my yard are absolutely overrun this spring with this plant. “Pland.ID” online identified a photo as “Parietaria pensylvanica Muhl. ex Willd.” and indicated it is a member of the nettle family. Does anyone know anything about this “weed” — in particular, is it useful medicinally? Is it close enough to nettle to be interchanged medicinally? (My Urtica dioica is NOT growing very well this spring – so an effective substitute would be nice!) At the very least I need to get this invader under control… at worst, I need to do radical “yard surgery” before it seeds! Thanks for your help!
