Light. Looks best in full sun. It tolerates some shade but flowers less and gets leggy.
Water. Water regularly while it establishes. After that it is moderately drought tolerant.
Soil and feeding. Any well-drained soil works. It does not tolerate salt water or salt spray, so keep it away from the shore.
Size. About 6 ft tall and 4–6 ft wide; in frost-free areas it can reach 5–9 ft.
Pruning. Its airy, mounding form needs no pruning. For a neater shape, prune in spring, which reduces that year's flowers. It can also be trained as a small tree or loose hedge.
Problems to watch. Few pests or diseases. The branches are brittle, so keep it out of high-traffic spots.
Good to know. Yellow flower clusters appear in summer and fall, and year-round in warmer areas. New stems are red. Deer tend to leave it alone.
