Light: At least 6 hours of direct sun, preferably morning sun with afternoon shade. Avoid hot west-facing walls and reflected pavement heat.
Water: Water deeply and regularly at the root zone; not drought tolerant. Increase irrigation during Phoenix summers, allowing the upper 1–2 inches of soil to dry slightly between waterings. Keep foliage dry.
Soil: Well-drained soil enriched with compost; slightly acidic soil is ideal. Phoenix’s alkaline soils may require treatment for nutrient deficiencies. Mulch 2–3 inches deep, keeping mulch away from the crown.
Mature size: Typically 10–15 feet tall and 6–8 feet wide with support; occasionally larger under favorable conditions.
Bloom: Heavy spring bloom, with possible lighter repeat flowering in fall. Repeat bloom varies by selection; plants sold as ‘Blaze Improved’ generally repeat more reliably. Extreme summer heat reduces flowering.
Evergreen / deciduous: Deciduous, but may retain some foliage through mild Phoenix winters.
Growth rate: Fast once established with adequate water and nutrients.
