Campanula pers. coerulea

Description and Characteristics

Campanula persicifolia 'Coerulea', commonly known as Peach-leaved Bellflower 'Coerulea', is a graceful, upright perennial prized for its airy habit, sky-blue bell-shaped flowers, and long-lasting summer display. As a cultivar of Campanula persicifolia, this selection is distinguished by its clear blue blooms that rise above neat clumps of narrow, glossy green foliage, resembling the leaves of a peach tree—hence the name.

‘Coerulea’ produces tall, wiry stems with large, outward-facing bellflowers from early to mid-summer, often blooming for 4–6 weeks. Its vertical form makes it ideal for cottage gardens, naturalistic plantings, and border backdrops, where it adds height without heaviness. The flowers also make excellent cut flowers and are attractive to a variety of pollinators.

It typically grows to a height of 75–100 cm, with a basal clump spread of around 30–40 cm, forming a tidy presence in mixed beds. With its soft colouring and movement in the breeze, 'Coerulea' is particularly effective planted in drifts or naturalised settings.
