Light: Full sun once acclimated; provide young plants with light afternoon shade during intense Phoenix summers.
Water: Low water; water deeply but infrequently during warm weather, allowing soil to dry completely between waterings. Keep nearly dry in winter.
Soil: Very well-drained, sandy or gravelly soil. Plant on a raised mound where native soil drains poorly.
Mature size: Typically 15–25 feet tall and 10–20 feet wide; may grow larger with age in favorable conditions.
Bloom: Large flowers appear in late spring through summer on mature plants; young specimens may take many years to flower.
Evergreen / deciduous: Evergreen; photosynthetic stems remain year-round.
Growth rate: Slow to moderate in warm weather with occasional deep watering.
