Care tips
This plant thrives in full sun, requiring at least 6 hours of direct sunlight for optimal blooming. It prefers well-drained, sandy, or stony soils and is quite drought-tolerant once established, so watering should be moderate. A common mistake to avoid is overwatering or planting in heavy, poorly drained soils, which can lead to root rot. It does not require excessive fertilization, as it adapts well to poor soils.
