While touring a local arboretum I saw a S. c. with maroon calyxes. It was quite pretty even without blossoms. Unfortunately it was one of the few plants not tagged. Does anyone know what this variety is?
Another that was spectacular was Canary Island Sage. I guess it gets pretty ratty looking by mid-summer, but could be a Spring-blooming knock-out if used in the back of the border. It certainly was huge.... tall and wide.
