Water: Moderate to regular water; irrigate deeply when the upper 1–2 inches of soil dry. Increase watering during extreme heat, but avoid constantly soggy soil.
Soil: Well-drained soil enriched with compost. Mulch the root zone, keeping mulch away from stems; strongly alkaline soil may cause nutrient deficiencies.
Mature size: Typically 15–25 feet long and 6–10 feet wide on a support; size can be controlled with pruning.
Bloom: Primarily spring through fall; flowering may slow during Phoenix’s hottest summer weather.
Evergreen / deciduous: Evergreen in frost-free locations; may lose leaves or suffer stem dieback during Zone 9b freezes.
Growth rate: Fast with adequate warmth, moisture, and nutrients.
