Moderate water; irrigate deeply when the upper 1–2 inches of soil dry. Water more frequently during establishment and extreme summer heat; reduce watering in winter. Not suitable for unirrigated desert landscapes.
A twining vine native to the eastern United States, with clusters of slender coral-red flowers that attract hummingbirds. In Phoenix, it performs best in a protected, irrigated location rather than an exposed desert setting.
Light: Morning sun with afternoon shade in Phoenix; avoid reflected heat from south- and west-facing walls. Heavy shade reduces flowering.
Water: Moderate water; irrigate deeply when the upper 1–2 inches of soil dry. Water more frequently during establishment and extreme summer heat; reduce watering in winter. Not suitable for unirrigated desert landscapes.
Soil: Well-drained soil enriched with compost. Prefers slightly acidic to neutral conditions but tolerates some alkalinity; mulch the root zone while keeping mulch away from stems.
Mature size: Typically 10–20 feet tall on support and 3–6 feet wide; size depends on growing conditions and pruning.
Bloom: Mainly spring through early summer, with intermittent repeat flowering into fall under favorable conditions. Extreme Phoenix summer heat may reduce blooming.
Evergreen / deciduous: Semi-evergreen to evergreen in mild winters; may lose foliage during cold snaps or environmental stress.
Growth rate: Moderate to fast with adequate water and suitable temperatures; slower during extreme heat.
