I tried to find a link to some information on "skullcap' .. and it seems rather difficult for some reason. I know this is a "native" plant and a great perennial that keeps itself tidy and minds its own business (a wonderful asset in the garden). It has Sunrise Echinacea and purple fennel for neighbors. Culvers Root (Veronicastrum virginicum) for those who like the BIG names ? LOL .. peeking over from the other side with Baby Swan coneflower and Petite Delight Monarda one of the more resistant to powdery mildew Bee Balms .. I love the smell of BB but the powdery mildew thing ... ugh !
