I snagged some plants from my SIL's and in a clump there was this. I don't know if it is a weed or if it is something else I want to plant in my yard. Can you ID it please. Thanks!
Possibly Campanula punctata... it is grown intentionally for the showy flowers, but it is quite invasive from the roots.
Oh, I hope so. I've wanted that one. And I have the room for it here to spread. Thanks :-)
