Light: Full sun; at least 6–8 hours daily produces dense growth and abundant flowers. Tolerates reflected heat in Phoenix.

Soil: Well-drained sandy, gravelly, or rocky soil; tolerates alkaline soil. Avoid poorly drained clay and persistently wet roots.
Mature size: Typically 5–8 feet tall and wide; compact cultivars remain approximately 3–5 feet tall and wide.
Bloom: Flowers in intermittent flushes from late spring through fall, especially during summer monsoon humidity and after rain.
Evergreen / deciduous: Generally evergreen in Phoenix; may lose some foliage during cold weather or severe drought.
Growth rate: Moderate; varies with cultivar, water availability, and growing conditions.
