Care tips
This plant thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal growth. Watering should be moderate, allowing the soil to dry out completely between waterings to prevent root rot. Use a well-draining substrate, preferably sandy or with good perlite content. A common mistake is overwatering, which can be fatal for this drought-tolerant species.
