This plant forms a low, cushion-shaped mound of small green leaves, with loads of open bells appearing in early summer. This selection has clear white flowers and will continue blooming for weeks if spent blossoms are regularly removed. This plant makes a good choice for the rock garden, edging and in containers. Performs especially well in regions with cool nights during the summer. Plants should be divided every 2 to 4 years, in spring or fall. Prefers good drainage.
