I bought this plant to go in a difficult area. We are quite dry in East Anglia and I could not get anything to grow in the narrow bed by the front door. The pokeweed has grown well and I think it is very attractive with its purple stems, green foliage and racemes of small purple flowers which form into dark berries. So far, it has not spread everywhere. It has lasted over winter last year but it was mild. Not sure whether to cut it back in autumn but we had enjoyed it this last 2 years.
