Grows easily in average, well-drained soils. Water deeply, regularly during the first growing season to establish an extensive root system. Once established, water regularly, but allow to dry out slightly between intervals for best foliage color. Drought tolerant in cool climates. Prune away old, faded foliage before new growth emerges in spring.
