Care tips
It thrives in full sun to partial shade and is highly drought-tolerant once established. Watering should be moderate, allowing the top layer of soil to dry out between waterings, and sparse in winter. It adapts to a wide range of well-drained soils, including poor or calcareous types. A common mistake to avoid is overwatering, as it is prone to root rot in waterlogged conditions.
