Care tips
It thrives in full sun exposure for optimal growth and abundant flowering. Watering should be moderate, allowing the substrate to dry out completely between waterings, as it is very drought-tolerant once established. It requires well-drained soil, preferably sandy or stony, and does not tolerate waterlogging. A common mistake is overwatering, which can lead to root rot; it's better to err on the side of dryness than wetness with this species.
