Light: Full sun; at least 6 hours of direct sunlight promotes abundant color. Light afternoon shade can help newly planted specimens during Phoenix summers.
Water: Water deeply, then allow the soil to dry substantially before watering again. Established plants are drought tolerant; new plants and containers need more frequent watering in extreme heat.
Soil: Well-drained sandy or loamy soil; tolerates alkaline soil but dislikes persistently wet roots.
Mature size: Typically maintained at 4–6 feet tall and wide as a bush; unpruned plants may reach 10 feet or more, depending on growing conditions and support.
Bloom: Repeated flushes from spring through fall, sometimes continuing into winter in frost-protected Phoenix locations.
Evergreen / deciduous: Evergreen in frost-free conditions; may lose leaves during cold weather or drought.
Growth rate: Fast during warm weather with adequate moisture.
