Care tips
It requires full sun to partial shade for optimal flowering. Watering should be moderate, allowing the substrate to dry out between waterings, as it is drought-tolerant once established. It prefers well-drained, sandy or stony soils, with a neutral to slightly acidic pH. A common mistake is overwatering, which can lead to root rot.
