Light: Morning sun with afternoon shade in Phoenix; protect from intense western exposure and reflected summer heat.
Water: Low water once established; water thoroughly, then let soil dry between waterings. Container plants need closer monitoring during summer. Reduce watering sharply in cool weather.
Soil: Very well-drained, sandy or gritty soil; use cactus/succulent potting mix amended with pumice or perlite in containers.
Mature size: Typically 2–4 feet tall and 2–3 feet wide; larger varieties can reach 6 feet tall, while dwarf cultivars stay around 1–2 feet.
Bloom: Repeated bloom throughout warm weather; potentially year-round with sufficient light, warmth, and moderate watering.
Evergreen / deciduous: Evergreen in warm conditions; may drop leaves during drought, cold, or other stress.
Growth rate: Slow to moderate.
