Small clusters of starry white flowers appear in early summer. Excellent for hot, sunny locations. Perfect for the rock garden, wall, alpine containers or edging a pathway. Easily divided in spring. Plants remain evergreen in mild winter regions. Prune back to 2 inches in spring, if desired. Possibly hardy to Zone 4 or colder. Introduced by international breeder Syngenta Flowers.
