Tall spires of pink and white flowers rise above narrow foliage all summer long, holding up to heat and humidity without complaint. Each bloom is distinctly two-toned, creating a striped effect that reads from a distance.

Deadheading encourages more blooms, but the plant keeps flowering even if you skip it. Space 12–18 inches apart in full sun and average soil, and you'll have cut flowers and garden color from May through frost.
