This drought tolerant perennial, with dark evergreen leaves, grows only 15 inches tall. For what it lacks in height, it compensates in color saturation. It has been described as rose-red, magenta, and vivid-deep pink. Some have reported seeing coral-pink in the setting sun. No matter how we describe it, one cannot escape its intensity.This plant begins blooming in early summer, re- blooms in October and lasts until the first frost. For maximum enjoyment, grow it in full sun, in the front row of the flower bed. Hardy from Zones 5 to 9.
