'Missouri Rose' is a much darker and more vibrant red-purple out here in Oregon. Cynda and Lynn were here a couple weeks ago and they both thought 'Missouri Rose' was beautiful. In MA it colored up early and stayed colorful but here it develops color at around the end of May and intensifies all summer.
I'm not sure of its parentage but think it was from 'Sanford Hybrid' as Pat used that a lot. the name was supposed to be 'Wine and Roses" but Helen didn't want to sell anything with WINE in the name!
All of my red and purple heufelliis have great color (you should try these Bev if you want good summer color) and my new hybrid 'Borscht' is a huge beet root red-purple. As Lynn says "Everyone at the clinic wanted that one, Kevin." It was red even as a tiny seedling.
