Silphium perfoliatum - 2018


By Andrewr

Silphium perfoliatum - 2018 (Silphium perfoliatum)

A plant for the back of the border, this grows to seven feet even in a dry season. For sun or part shade, in a soil that doesn't dry out. Probably best with some support to keep the stems upright. This clump is twenty yeas old and getting better and better every year
