Light: Full sun to partial shade; afternoon shade is helpful in Phoenix, especially near heat-reflecting walls.
Water: Moderate water for lush growth and abundant blooms. Water deeply, then allow the upper few inches of soil to dry; irrigate more often during extreme summer heat. Established plants tolerate short dry spells.
Soil: Adaptable to most soils, including Phoenix’s alkaline soils; well-drained soil enriched with compost supports best growth.
Mature size: Typically 3–4 feet tall and 2–3 feet wide; spreading roots can form wider colonies.
Bloom: Late spring through fall, often longer in warm, frost-protected locations. Individual flowers last one day, with new blooms opening regularly.
Evergreen / deciduous: Evergreen to semi-evergreen in protected Phoenix locations; frost may kill stems back, with regrowth from the roots in spring.
Growth rate: Fast.
