Care Instructions

Light: In Phoenix, provide gentle morning sun and afternoon shade; avoid reflected heat and hot western exposures.

Water: Moderate to high water needs in Phoenix; irrigate deeply to maintain evenly moist, not soggy, soil. Not a desert-adapted or reliably drought-tolerant choice.

Soil: Moist, organically enriched, well-drained soil. Phoenix’s alkaline soils may contribute to nutrient deficiencies; avoid poorly drained planting sites.

Mature size: The species typically reaches 10–20 feet tall and 8–15 feet wide. A dwarf size cannot be specified without a confirmed cultivar.

Bloom: Typically late spring to early summer on the previous year’s growth. Flowering and overall performance may be unreliable in Phoenix.

Evergreen / deciduous: Deciduous.

Growth rate: Moderate under suitable conditions; potentially slow or weak in Phoenix.
