Light: Full sun for best flowering; light afternoon shade can help in intensely hot, reflected-heat locations.
Water: Low to moderate water once established. Water deeply, then allow the upper soil to dry; irrigate more regularly during establishment and extreme summer heat.
Soil: Well-drained sandy, gravelly, or loamy soil; tolerates alkaline soil. Avoid persistently wet or poorly drained sites.
Mature size: Typically 1–2 feet tall and 2–3 feet wide; may grow larger with a long frost-free season.
Bloom: Repeatedly from spring through fall; flowering may continue into winter in frost-free, sheltered locations.
Evergreen / deciduous: Evergreen in frost-free conditions; may lose leaves or die back during Zone 9b freezes.
Growth rate: Fast during warm weather.
