This is a lovely group of bellflower that generally grow about 18 to 24 inches tall and 12 to 18 inches wide. It has an upright, sort of erect habit and dark green, ovate to arrow-shaped leaves. Flowers are and open bell-shape, and appear in upward facing clusters at the ends of stems. Blooms late spring to early summer, though some cultivars bloom later. The species is usually a periwinkle blue, but there are a number of cultivars available, including 'Alba' with white flowers, 'Superba' with dark blue flowers, and 'Joan Elliot' with deep violet-blue flowers. A wonderful addition to a perennial border. A nice cut flower.
Grow in full sun to part shade, in well drained, loamy garden soil. Manages with very little water when sheltered from mid day sun. After blooming, you can snip away about a third of the plant, if you'd like a tidier appearance. Deadheading prolongs the blooming period, and as they make lovely cut flowers, don't wait for the flowers to fade. Otherwise, cut back in late winter to early spring, as new growth emerges.
