Light: Full sun for best flowering; tolerates light afternoon shade in Phoenix.
Water: Low to moderate water once established. Water deeply, then allow soil to dry between waterings; provide supplemental irrigation during prolonged summer heat for better flowering.
Soil: Well-drained sandy, loamy, or gravelly soil; tolerates alkaline soil. Avoid persistently wet or poorly drained sites.
Mature size: 4–6 feet tall and 5–7 feet wide, potentially larger in protected locations.
Bloom: Spring through fall, often into winter in frost-free locations; extreme heat or drought may temporarily reduce flowering.
Evergreen / deciduous: Evergreen to semi-evergreen in mild Phoenix winters; frost may cause leaf drop or kill stems back, with regrowth from established roots in spring.
Growth rate: Fast in warm weather.
