Care tips
This plant thrives in full sun and requires well-drained soil, preferably sandy or rocky, similar to its natural habitat. Although drought-tolerant once established, it benefits from moderate watering during dry periods, allowing the substrate to dry completely between waterings. Avoid overwatering, as it is susceptible to root rot. A common mistake is planting it in heavy, clayey soils, which hinder proper drainage.
