Light: Morning sun with filtered light or afternoon shade; aim for 6 hours of sun for good flowering. Acclimate gradually to prevent sunburn in Phoenix heat.
Water: Water deeply during warm, leafy growth, then let the upper several inches of soil dry before watering again. Containers may need frequent checks during extreme heat. Keep nearly dry during cool, leafless dormancy.
Soil: Very well-drained soil; use a coarse cactus mix amended with pumice or perlite in containers. Avoid heavy clay, standing water, and poorly drained planting sites.
Mature size: Usually 6–12 feet tall and 4–8 feet wide in Phoenix containers or protected sites; can reach 15–25 feet tall and similarly wide in frost-free ground.
Bloom: Typically late spring through fall during warm weather; flowering varies with cultivar, sunlight, and plant maturity.
Evergreen / deciduous: Deciduous; usually drops leaves during cool weather and remains dormant through winter.
Growth rate: Moderate during warm weather; growth stops during winter dormancy.
