Perennial - Easily grown in moderately fertile, dry to medium moisture, well-drained soils in full sun. Plants tolerate some light shade. Plants also tolerate poor soils as long as they are sharply drained. Drought tolerant once established. Plants perform well in hot and dry sites. Avoid wet soils. Winter mulch is important in the northern parts of this plant’s growing range. Prune back plants to old wood in early spring.
