Care tips

It requires full sun exposure and well-drained, preferably sandy or stony soils, with a neutral to slightly alkaline pH. This plant is drought-adapted, so watering should be sparse, allowing the substrate to dry out completely between waterings. Avoid excessive moisture in the substrate, as it is prone to root rot. It does not tolerate frost.
