Garden Uses: Mass in border fronts or rock gardens. Underplanting. Edging and bedding. Mixed containers.
​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.
​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.
​These blossoms do not perform well as cut flowers, and are best enjoyed outdoors.
​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.
The young leaves, stems and flowers of Sweet Alyssum are sometimes used to flavor or decorate many dishes. For starters, it can be added into something easy such as a salad, folded in an omelet, or added to soups. Sweet Alyssum flowers candy very well or you can free them in water and make jazzy ice cubes! Finally you can dress up any dish or snack tray by adding Sweet Alyssum as a garnish. ​
​Sweet Alyssum is used for many medicinal purposes. It is used to treat common cold, abdominal pain, and coughs. It also is used as in the treatment of rabies. Mostly, it is used in managing disorders associated with retention of fluids such as edema and ascites because it helps eliminate excess water from the body.
