Saponaria Soapwort flowers are well suited to cutting and are excellent as a filler in arrangements similar to the way baby's breath is used. White Soapwort liberally re-seeds itself, so the plant will easily come back each season from its own Saponaria seeds.
Growing Soapwort from seed is fun and rewarding. Saponaria Soapwort seeds can be sown either indoors or directly outdoors. For indoor sowing, the Saponaria seeds germinate better after cold treatment. Dampen a paper towel, place the seed on the towel and roll it up. Place the damp towel with the seeds into a Ziploc bag and place it in the refrigerator for 4 weeks.
After the cold treatment, sow the white Soapwort flower seeds on the surface of the starter mix in small pots or trays. Only lightly cover the Soapwort seeds as they need light for germination. For outdoor sowing, prepare the soil by loosening and weeding and place 2 - 3 seeds in groups spaced 18 inches apart. Press seed into the soil and lightly cover.
Keep seeds moist until germination. Outdoor sowing can be done either in fall or spring. Water Soapwort regularly to help it establish and lightly fertilize it a couple of times during the growing season.
