Native. Pretty aggressive. I'm trying to get these gone from all the flowerbeds, but it's a battle. At least they pull fairly easy.

I've decided to let these be here because I'm tired of fighting with them. I would like to keep them away from the driveway a bit though. I don't mind them too much, except they just won't give it a rest and they look real ratty after they bloom unless I go deadhead them all. Also I don't like the smell of the foliage.
