Care Instructions

Light: Full sun to partial shade; afternoon shade is beneficial in Phoenix’s intense summer heat.

Water: Moderate water; irrigate deeply, then allow the upper few inches of soil to dry. Water more frequently during extreme heat and establishment; established plants tolerate brief dry periods.

Soil: Adaptable to most soils, including alkaline soils, provided drainage is adequate; compost improves poor desert soil.

Mature size: 8–12 inches tall and 12–24 inches wide.

Bloom: Repeatedly from spring through fall, with the strongest flowering during warm weather.

Evergreen / deciduous: Evergreen in frost-free locations; foliage may die back after frost in Zone 9b, with regrowth in spring.

Growth rate: Moderate to fast during warm weather with regular irrigation.
