This image shows a favorite in my garden, Snow-in-Summer, a perennial, proper name: Cerastium. Snow in Summer really puts on a display. They are perfect for rock gardens, being small plants that grow just six to eight inches. It's silvery gray leaves, give way to a profusion of white blooms in late spring to early summer. Snow-In-Summer has wooly, silvery gray-green leaves that are attractive, even when not in bloom. This native of Italy, produces mounds of flowers in May-June. The profusion of white booms mounded atop the plant, gives it it's name. Other Names: Snow-in-Summer is also known as Cerastium, Mouse Ear, Chickweed, and Silver Carpet. Snow In Summer is common in rock gardens, and as a ground cover. Many people also use it as border edgings, or along sidewalks. Because it can be invasive, you may have to control the spread of this plant, if you grow it in your flower garden along with other flowers. These small plant look their best in the front of the flower garden.
