Nothing adds more delight to summer days than the gentle fragrance of sweet alyssum. A wonderful annual ground cover, alyssum blooms all growing season, withstands drought and heat, and is an ideal rock garden plant. Alyssum graces containers and planters by hanging over their edges, and to top it off, it is very easy to grow! Edible flowers have a mild, grassy/mustardy flavor; the clusters make a charming garnish to salads and desserts.
