Light: Full sun, with at least 6 hours of direct sunlight for best flowering. Container plants may benefit from light afternoon shade during extreme Phoenix heat.
Water: Low water once established. Water deeply, then allow soil to dry substantially before watering again. Water new plants and containers more frequently, especially during summer; avoid constantly moist soil.
Soil: Well-drained sandy or gravelly soil. Tolerates alkaline soil but struggles in waterlogged clay; use raised planting areas where drainage is poor.
Mature size: Typically 10–20 feet tall and 8–15 feet wide with support; can be maintained smaller with pruning.
Bloom: Repeated flushes from spring through fall, sometimes continuing into winter in frost-free, sheltered locations.
Evergreen / deciduous: Evergreen in frost-free conditions; may lose leaves during Phoenix cold spells or drought.
Growth rate: Fast in warm weather with adequate moisture.
