Light: Morning sun with afternoon shade or bright filtered light; avoid intense reflected heat and full afternoon sun in Phoenix.
Water: Water deeply and regularly during hot weather, allowing the upper few inches of soil to dry between waterings. Reduce watering in winter; established plants tolerate brief dry periods but are not desert xeric plants.
Soil: Well-drained soil enriched with compost; tolerates sandy or clay soils if drainage is adequate.
Mature size: 2–3 feet tall and 2–3 feet wide; flower stalks may reach 4 feet.
Bloom: Repeated flushes primarily in spring and fall in Phoenix; individual flowers usually last one day, and flowering may slow during extreme summer heat.
Evergreen / deciduous: Evergreen in mild winters; hard freezes can damage foliage.
Growth rate: Moderate with adequate moisture and protection from extreme heat.
