Care tips

This plant prefers full sun to partial shade and well-drained soils, although it is tolerant of a wide range of conditions once established. Water regularly during dry periods, but allow the substrate to dry out slightly between waterings to avoid waterlogging, to which it is sensitive. A common mistake is planting it in heavy, poorly drained soils, which can lead to root rot. It is drought-tolerant once mature.
