Care Instructions

Light: Full sun; best with at least 6–8 hours of direct sunlight daily.

Mature size: Approximately 25–35 feet tall and wide; size varies with irrigation, soil, and pruning.

Bloom: Spring to early summer; flowering varies with moisture and growing conditions.

Evergreen / deciduous: Deciduous to semi-deciduous in Phoenix; winter leaf retention depends on temperatures.

Growth rate: Moderate to fast, especially with supplemental irrigation.
