Water: Low water once established. Water deeply and infrequently, allowing soil to dry between irrigations. Provide regular establishment watering, then extend intervals; avoid frequent lawn-style watering.

Soil: Well-drained sandy, gravelly, or loamy soil; tolerates alkaline desert soils. Avoid persistently wet soil and poorly drained planting sites.

Mature size: Usually 25–40 feet tall and 30–40 feet wide; allow ample room for the spreading canopy.

Bloom: Spring to early summer, typically April–June in Phoenix.

Evergreen / deciduous: Semi-evergreen to deciduous in Phoenix; leaf retention varies with winter temperatures and drought.

Growth rate: Fast with supplemental irrigation; slower under dry conditions.
