Campanula carpatica ‘Rapidol Blue'’ (Carpathian Bellflower)

This bellflower is considered an improvement on the older ‘Clips’ series displaying excellent vigour and blooming up to 4 weeks earlier. Plants form a low, cushion-shaped mound of small green leaves, with loads of upfacing, open blue bells appearing in late spring through late summer. Will continue blooming for weeks if spent blossoms are regularly removed. Excellent 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.

USDA Zones: 3 - 9
