|Bold, tropical-looking dark burgundy foliage contrasts with the huge, self-cleaning coral-rose flowers. Blooms summer to frost. Effective in mass plantings, borders, or in containers. Easy to grow. Plant in full sun for best growth and flowering. Hardy in zone 6b. Clumps grow to 3 feet tall. Keep soil moist until completely established. Drought tolerant when established. Fertilize in spring just before new growth begins and again in summer as blooming begins. Remove spent flower stalks. Cut foliage to the ground after the first killing frost.
