Light: Full sun for best flowering; tolerates light afternoon shade in Phoenix.
Water: Low to moderate water once established; water deeply and let the upper soil dry between irrigations. Supplemental summer water supports fuller growth and more blooms.
Soil: Well-drained soil; tolerates sandy, rocky, and alkaline soils. Avoid persistently wet or poorly drained locations.
Mature size: Typically 10–15 feet tall and 6–10 feet wide in Phoenix; can grow larger in frost-protected locations.
Bloom: Spring through fall, often continuing until frost; flowering may slow during extreme heat or drought.
Evergreen / deciduous: Semi-evergreen to deciduous in Phoenix; may remain evergreen in warm microclimates. Freezing temperatures can kill stems back.
Growth rate: Fast with adequate warmth and irrigation.
