Care tips
This species thrives in full sun for optimal growth and abundant flowering. It is very drought-tolerant once established, so watering should be sparse, avoiding waterlogging which can be fatal. It requires well-drained soil, preferably sandy or stony, and does not tolerate heavy or overly moist soils. A common mistake to avoid is overwatering, especially in winter, which can lead to root rot.
