Light: Full sun to light shade; light afternoon shade is beneficial in especially hot, reflected-heat locations.
Water: Low water once established; water deeply but infrequently, allowing soil to dry between waterings. Provide occasional supplemental water during prolonged summer drought; avoid persistently wet soil.
Soil: Well-drained sandy, gravelly, or rocky soil; tolerates alkaline desert soils. Avoid heavy, poorly drained soil and excessive fertilizer.
Mature size: 2–4 feet tall in bloom and 1–2 feet wide; foliage remains much lower than the flower stalks.
Bloom: Late winter through spring, typically February–April in Phoenix; timing varies with weather.
Evergreen / deciduous: Generally evergreen; may lose some foliage or become semi-dormant during extreme summer heat and drought.
Growth rate: Moderate to fast during the cool growing season.
