Light: Full sun to partial shade; morning sun with afternoon shade helps prevent leaf scorch in Phoenix summers.
Water: Moderate to high water needs; keep soil consistently moist during active growth. Water deeply and frequently during extreme heat, especially in containers. Reduce watering during winter dormancy.
Soil: Rich, moisture-retentive but well-drained soil amended with compost. Mulch to conserve moisture and keep roots cooler.
Mature size: Approximately 4–6 feet tall and 2–3 feet wide; rhizomes gradually spread into larger clumps.
Bloom: Late spring through fall in warm conditions; flowering may slow during extreme summer heat or when moisture is insufficient.
Evergreen / deciduous: Herbaceous perennial; frost-deciduous in Zone 9b, though foliage may persist through exceptionally mild winters.
Growth rate: Fast with warmth, adequate moisture, and nutrients.
