Snow-in-summer is a diminutive creeping plant that works best along the edge of a flower bed or in a rock garden, where it will not be shaded by other plants. With small, densely growing silver leaves creeping along the ground, it is attractive even when it isn't covered with glistening white 5-petalled flowers in late spring to early summer. It is very cold hardy and tolerant of poor soils. This plant is native to mountainous regions in Europe; in the pink family, it is related to carnations.
