'Iridescent Bells' ('Irbella') Bellflower blooms in June and July, with fragrant light lavender bell-shaped flowers which emerge from eggplant purple buds. Visited by bees and hummingbirds, 'Iridescent Bells' is the perfect addition to cottage gardens and the perennial boarder; a good cut flower. The green foliage is clean and Campanula 'Iridescent Bells' has an upright habit, displaying the hanging flowers nicely. If deadheaded after blooming this Bellflower reblooms in the late summer and early fall. A Burpee Introduction which has been praised by the Royal Horticultural Society.
