Care Instructions

Light: Full sun to light shade; in Phoenix, provide afternoon shade from intense summer sun, especially for young or newly planted specimens.

Water: Low water once established; water deeply, then let soil dry thoroughly. In Phoenix, provide occasional supplemental summer irrigation and reduce watering during cool weather.

Soil: Very well-drained, sandy or gravelly soil; use a raised mound where native soil is compacted or drains poorly.

Mature size: Typically 8–12 feet tall and 4–6 feet wide; old specimens can reach 15 feet or more.

Bloom: Typically winter to early spring once mature; flowering may take several years and does not kill the plant.

Evergreen / deciduous: Evergreen.

Growth rate: Slow to moderate, depending on warmth, drainage, and water availability.
