Care Instructions

Light: Full sun; light afternoon shade is beneficial in Phoenix’s hottest exposures. Avoid intense reflected heat from west-facing walls.

Water: Low water once established; water deeply, then allow the soil to dry well between irrigations. Young plants and containers need more frequent watering, especially during extreme summer heat.

Soil: Very well-drained sandy or gravelly soil; tolerates alkaline soil. Use raised planting areas where drainage is poor, and keep the crown above standing water.

Mature size: 4–6 feet tall and 3–4 feet wide.

Bloom: Primarily late winter through spring in Phoenix, with occasional repeat flowering in cooler months.

Evergreen / deciduous: Evergreen.

Growth rate: Moderate; faster with good drainage and appropriate irrigation.
