Light: Full sun for best flowering; tolerates light afternoon shade in Phoenix.
Water: Low to moderate water once established. Water deeply, then allow the upper several inches of soil to dry; supplemental summer irrigation supports fuller growth and better flowering.
Soil: Well-drained soil; tolerates sandy, rocky, and alkaline desert soils. Avoid persistently wet soil.
Mature size: Typically 6–9 feet tall and 4–6 feet wide; may grow larger in frost-protected locations.
Bloom: Spring through fall, often until frost; flowering may slow during extreme heat or drought.
Evergreen / deciduous: Semi-evergreen to deciduous in Phoenix; frost can cause leaf loss and stem dieback.
Growth rate: Fast with warmth and adequate irrigation.
