Care tips
It prefers full sun to partial shade exposure and adapts to a wide range of soils, though it thrives best in well-drained, not overly rich substrates. Watering should be moderate, allowing the soil to dry out slightly between waterings, as it is quite drought-tolerant once established. Avoid waterlogging, which can lead to root rot. It does not require much fertilizer.
