About Tall White Sweet Alyssum: This attractive member of the mustard family originally came from the rocky coasts of the Mediterranean region. The common name Alyssum comes from a Greek word meaning “rabies,” referring to the ancient belief that this plant had the ability to treat this disease. The genus name Lobelia honors the renowned Flemish botanist Mathias de Lobel.
Tall White Sweet Alyssum Germination: Direct sow in spring, after the soil warms. Press the seed into the surface of the soil, since it needs light to germinate. Keep the soil lightly moist until germination. The seed can also be started indoors 6-8 weeks before the last frost date of spring. Keep the soil lightly moist, and transplant the seedlings as soon as there is no chance of frost.
Growing Tall White Sweet Alyssum Seeds: Keep the plants watered, since they do not appreciate dry soil. To encourage rebloom, cut the plant back by one third. In the heat of summer, blooming will decrease. This plant makes an excellent ground cover or container plant, and attracts butterflies and bees. It may reseed in good growing conditions.
Harvesting Tall White Sweet Alyssum: These blossoms do not perform well as cut flowers, and are best enjoyed outdoors.
Saving Tall White Sweet Alyssum Seeds: After the flowers fade, the plant will produce seed pods. Watch the pods carefully, since they eventually split and release their seeds. Harvest the seeds as soon as they ripen to their mature light brown color. The entire plant can also be removed and spread out to dry, and the seeds removed from the pods. Store the seeds in a cool, dry place.
