Care tips
This plant thrives in full sun and prefers well-drained soils, even poor or calcareous ones. Watering should be moderate, allowing the substrate to dry out between waterings, as it is drought-tolerant once established. A common mistake to avoid is overwatering, which can lead to root rot. It does not require much fertilization and benefits from deadheading to prolong flowering.
