Care tips
It prefers full sun to light partial shade for optimal flowering. It requires moderate watering, allowing the substrate to dry slightly between waterings, and is drought-tolerant once established. It thrives in well-drained soils, preferably sandy or loamy, and is not demanding in terms of nutrients. Avoid overwatering, as it can lead to root rot, and deadhead spent flowers to encourage prolonged blooming.
