Light: Full sun for best flowering; light afternoon shade is beneficial near heat-reflecting walls in Phoenix.
Water: Low to moderate water once established. Water deeply, then allow soil to dry partially between waterings; irrigate more frequently during establishment and extreme summer heat.
Soil: Well-drained soil; tolerates sandy, rocky, and alkaline soils. Avoid persistently wet soil and poorly drained clay.
Mature size: Typically 2–3 feet tall and 4–6 feet wide.
Bloom: Blooms from spring through fall, often into winter in frost-protected Phoenix locations; flowering may slow during extreme heat.
Evergreen / deciduous: Evergreen in frost-free locations; semi-evergreen or winter-deciduous in Zone 9b, with possible frost dieback.
Growth rate: Fast during warm weather.
