Light: Full sun; tolerates light shade. Well adapted to intense Phoenix sun and reflected heat.
Water: Low water once established. Water deeply and allow soil to dry between waterings; occasional supplemental summer irrigation improves appearance and growth. Water more regularly during establishment and sparingly in winter.

Mature size: Typically 6–8 feet tall and 6–10 feet wide, with flower stalks reaching 12–15 feet.
Bloom: Late spring through summer on established plants. May take several years to first flower; flowering does not kill the plant.
Evergreen / deciduous: Evergreen.
Growth rate: Slow to moderate; faster with occasional deep irrigation during warm weather.
