Light: Morning sun with afternoon shade; tolerates more sun in winter. Protect from intense summer sun and reflected heat.
Water: Moderate water; water deeply when the top 1–2 inches of soil feel dry. Avoid waterlogged soil and standing water in saucers; containers need frequent moisture checks.
Soil: Well-drained soil enriched with compost; use a quality, freely draining potting mix in containers.
Mature size: Typically 1–2 feet tall and wide, depending on cultivar.
Bloom: Primarily fall through spring in Phoenix; flowering slows or stops during extreme summer heat. Deadhead regularly to encourage repeat bloom.
Evergreen / deciduous: Evergreen tender perennial in frost-free conditions; often grown as a cool-season annual in Phoenix.
Growth rate: Moderate to fast during mild weather; slows in extreme heat.
