This is the darkest red flowering phlox I know of, being an intense deep red-violet. So intense that on a sunny day it almost hurts your eyes. Compared to ‘Red Riding Hood’, this is about 8″ taller, and the red is deeper, and a touch more of crimson. As with most of the strongly colored phlox, there is a lot of dark pigmentation of the leaves and flower buds. Not much troubled by mildew.
