Atlanta - I had one in the backyard for about 2 years that did not get enough sun. Looked thin and did not bloom. Moved it (early spring) to full sun in the front yard and it grew and bloomed beautifully the first season. Big plant, lovely leaves and blooms. Gets about 3.5' tall and wide.

Easily grown in average, dry to medium wet, 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. Difficult to grow from seed and slow to establish. Plants take on more of a shrubby appearance and tend to open up after bloom. Light trimming or shearing foliage after bloom helps maintain rounded plant appearance and obviates any need for support, but eliminates the developing seed pods.
