Soapwort Seeds, Saponaria officinalis , perennial herb, soap making

Soapwort is a very fast-growing plant that readily self-seeds. It will grow successfully no matter when it’s planted, though it’s traditionally thought best to start it in early spring after the risk of frost has passed. Soapwort is so easy to establish that it is actually regarded as invasive in many regions, so take care to supervise its spread if you choose to plant it in your garden.
