This perennial produces excellent, summer-long blooms on low growing plants that work well in containers and rock gardens.
Season & Zone
Exposure: Full sun
Start indoors in peat or coir pots 8-10 weeks before planting out. Alternately, direct sow in early spring or early autumn. For best results, place the seeds on the surface of pre-moistened soil, and tuck inside a plastic bag. Refrigerate for three weeks, and then provide bright light and 21°C (70°F). Germination should occur in 10-21 days.
Transplant into dry, rocky soil in full sun or partial shade at 10-20cm (4-8”) apart. Water only during very dry spells, and do not fertilize. Cut back after blooming to keep plants compact. Saponaria plants do not transplant well.
