Light: Full sun to partial shade; morning sun with afternoon shade is best during Phoenix summers.
Water: Moderate to high water needs; keep soil consistently moist but not stagnant during active growth. Containers may need daily watering in extreme heat. Reduce watering substantially during winter dormancy.
Soil: Rich, moisture-retentive, well-drained soil amended with compost. Mulch to conserve moisture and keep roots cooler.
Mature size: Approximately 3–4 feet tall and 1.5–2 feet wide; rhizomes gradually expand the clump.
Bloom: Repeatedly from spring through fall in warm conditions; extreme summer heat may reduce flowering.
Evergreen / deciduous: Herbaceous perennial; often winter-dormant in Zone 9b. Foliage may persist in frost-free locations but is damaged by frost.
Growth rate: Fast during warm weather with sufficient water and nutrients.
