Growing

Saponaria caespitosa thrives in full sun with well-drained, rocky or limestone soil. It prefers neutral to slightly acidic pH and requires moderate watering, allowing soil to dry between waterings. Propagate by seed or planting; pruning is minimal and mainly for design. Protect from wet winters and ensure good drainage to avoid root rot.
