Care tips
It requires full sun for optimal flowering and prefers well-drained soils, even poor or rocky ones, tolerating drought once established. Watering should be minimal, only occasional during prolonged dry spells, as it is very drought-tolerant. Avoid overwatering and heavy soils, as these can lead to root rot; this plant thrives in arid conditions.
How to save a dying Spiny broom

- What kills it
- Overwatering and lack of direct sun. Constant moisture rots its roots, and shade weakens it.
