Light: Full sun to partial shade; morning sun with afternoon shade is preferable in Phoenix, especially near heat-reflecting walls.
Water: Moderate water; irrigate deeply when the top 1–2 inches of soil dry. Containers may need daily watering during extreme heat. Avoid soggy soil.
Soil: Well-drained soil with modest organic matter. Avoid excessive nitrogen, which encourages foliage at the expense of flowers.
Mature size: Typically 6–10 feet tall on support and 3–6 feet wide; may grow longer under favorable conditions.
Bloom: Late spring through fall, depending on planting time; flowering may decline during extreme summer heat.
Evergreen / deciduous: Annual rather than reliably evergreen; frost kills the foliage and stems.
Growth rate: Fast during warm weather with adequate moisture.
