Easily grown in average, dry to medium moisture, well-drained soil in full sun to part shade. Best in full sun. Tolerates drought and poor soils. Over time, plants form slowly expanding clumps with deep and extensive root systems, and should not be disturbed once established. Plants take on more of a shrubby appearance and tend to open up after bloom. Trimming or shearing foliage after bloom helps maintain rounded plant appearance and obviates any need for staking, but eliminates some of the developing seed pods which are so attractive.
