Light: Full sun for best flowering; tolerates light shade but blooms less heavily.
Water: Low to moderate water once established. Water deeply, then allow soil to dry between irrigations. In Phoenix, established plants generally benefit from deep watering every 1–2 weeks during extreme summer heat, adjusted for soil and exposure; water much less in winter.
Soil: Well-drained soil; tolerates sandy, rocky, and alkaline soils. Avoid persistently wet or poorly drained locations.
Mature size: Typically 15–20 feet tall and 15–20 feet wide; occasionally larger. Compact cultivars remain smaller.
Bloom: Late spring through summer, often with repeat flowering into early fall. Removing spent flower spikes can encourage rebloom.
Evergreen / deciduous: Deciduous; normally loses its leaves in winter.
Growth rate: Moderate to fast, especially with regular deep watering.
