Can you grow soapwort from seed?
Rock soapwort can be directly seeded into your garden. Choose a sunny spot, though an area with afternoon shade is ideal in extremely hot climates. A well-draining, even sandy or rocky soil for planting is best. Growing soapwort is easy, and the plant makes a good addition to empty beds, woodland edges, or rock gardens. Soapwort seeds can be started indoors in late winter with young transplants set out in the garden after the last frost in spring. Otherwise, they can be sown directly in the garden in spring.Rock Soapwort prefers well-drained, medium to dry, slightly alkaline, loamy soil, but tolerates light-textured soil. Plant in full sun to maximize blossoms. Once established, it will also tolerate some drought.Kept moist in bright light at around 60°F, seeds typically germinate over the course of a few weeks. Once germinated, prick out to grow on in individual pots. Harden off before transplanting in spring or autumn. Soapwort will self-sow and spread over time, especially in moist semi-shaded soils.
