Light: Full sun, ideally at least 6 hours daily. In Phoenix, light afternoon shade can reduce heat stress; avoid intense reflected heat from west-facing walls.
Water: Moderate water in Phoenix; irrigate deeply and let the upper few inches of soil dry between waterings. Water regularly during establishment and prolonged summer heat; established plants tolerate some drought but bloom best with consistent moisture.
Soil: Well-drained soil; adaptable to sandy, loamy, or clay soils if drainage is adequate. Prefers slightly acidic to neutral conditions; Phoenix’s alkaline soils may cause iron chlorosis.
Mature size: Typically 15–25 feet tall and 10–20 feet wide for tree-form cultivars; dwarf and compact cultivars may remain 2–10 feet tall.
Bloom: Late spring through summer, sometimes into early fall; flowers on new growth. Extreme heat or drought may temporarily reduce flowering.
Evergreen / deciduous: Deciduous.
Growth rate: Moderate to fast with adequate water and favorable soil conditions.
