Light: Partial to full shade in Phoenix; gentle morning sun is acceptable. Protect from afternoon sun and reflected heat.
Water: Water deeply and regularly during active growth, allowing the soil surface to dry slightly between waterings. Reduce watering during summer dormancy; avoid persistently wet soil.
Soil: Well-drained soil enriched with compost. Mulch to moderate root temperatures, keeping mulch away from the crown.
Mature size: Foliage forms a mound about 3–4 feet tall and 3–5 feet wide; flower spikes can reach 4–6 feet tall.
Bloom: Typically late spring to early summer; flowering may be reduced or absent under extreme Phoenix heat or dense shade.
Evergreen / deciduous: Semi-evergreen in mild conditions; often summer-dormant in Phoenix heat. Foliage may also be damaged by frost.
Growth rate: Moderate during cooler growing periods; slows or becomes dormant in intense summer heat.
