Silphium astericus - Starry Rosinweed
I put in just one of these to see how it would do - it achieved 5-6 feet in height the second summer and is a butterfly magnet. It's already coming up this year and should be even more impressive.

Just planted this
I just planted this in my backyard. I live in MD, so I hope it is of the variety asteriscus. It is for the non-existent butterflies that we have now. Everything here is mono-culture (grass) .
