Care Instructions

Light: Bright filtered light or sheltered shade in Phoenix; gentle early-morning sun is acceptable, but avoid afternoon sun and reflected heat.

Water: Water deeply when the top 1–2 inches of soil dry. Check frequently during Phoenix summers; reduce watering in winter. Avoid soggy soil and prolonged drought.

Soil: Well-drained soil enriched with compost; use a quality, freely draining potting mix in containers.

Mature size: Typically 3–6 feet tall and 2–4 feet wide when maintained; supported climbing stems can reach 10–20 feet in favorable, frost-free conditions.

Bloom: Small, inconspicuous flowers may appear from spring through summer on established plants; flowering indoors is uncommon.

Evergreen / deciduous: Evergreen in frost-free conditions; freezing temperatures can damage or kill top growth.

Growth rate: Moderate to fast with adequate warmth, moisture, and filtered light.
