Light: Full sun to bright filtered light; in Phoenix, morning sun with afternoon shade helps prevent leaf scorch. Acclimate gradually to direct sun.
Water: Low water once established; water deeply, then let the root zone dry thoroughly. Water containers more frequently during extreme heat, but reduce watering sharply in winter.
Soil: Very well-drained, sandy or gravelly soil. Use cactus/succulent mix in containers and raised planting areas where native soil drains poorly.
Mature size: Typically 10–20 feet tall and 6–10 feet wide outdoors over many years; usually 3–6 feet tall in containers.
Bloom: Mature outdoor plants may bloom in summer after many years, often a decade or more; flowering is uncommon in containers and indoors.
Evergreen / deciduous: Evergreen.
Growth rate: Slow.
