Its semi-double, vibrant deep mauve flowers, on display for many weeks in late summer (Aug-Sept), are among the showiest of all Heathers. Wait until you see its foliage that changes through the seasons: a bright chartreuse and primrose yellow in spring, whose color intensifies in early fall as it gradually acquires brilliant shades of orange and red until late fall – early winter when the entire plant turns a spectacular, glimmering brick-red.
