Saponaria ocymoides (Rock Soapwort) is a mat-forming semi-evergreen perennial boasting masses of bright pink flowers held in loose sprays at the tips of its many branches. Blooming in early summer, they smother the foliage of small, ovate, olive-green leaves.
Drought tolerant once established. Water only occasionally; during summer water can be done more often.
Saponaria prefers to be planted in a full to partial sun location. In hot climates, afternoon shade is best.
Fertilize the crop weekly with 80-100 ppm nitrogen (at 2 kg/m3 slow release fertilizer in substrate).
Prune plants back hard immediately after blooming, to maintain a compact habit. Clumps may be easily divided in late summer or early spring.
