Care Instructions

Light: Full sun to partial shade; light afternoon shade can help young plants establish in Phoenix’s intense summer heat.

Water: Low water once established. Water deeply and allow soil to dry between irrigations; provide occasional supplemental summer watering in Phoenix. Water more regularly during establishment.

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

Mature size: Typically 10–20 feet tall and 8–15 feet wide, depending on water availability and training.

Bloom: Small, inconspicuous flowers in early spring.

Evergreen / deciduous: Semi-evergreen to evergreen in mild winters; may shed leaves during cold weather or severe drought.

Growth rate: Slow to moderate; growth is faster with appropriate supplemental water.
