Covering itself with fragrant snow-white blooms in early spring, this spreading alpine plant also has densely-packed leaves that form an attractive evergreen mat. It's an excellent plant for any sunny, well-drained spot, such as a raised bed, rock garden, or wall, and is good in combination with spring-blooming bulbs.

Notable Varieties
