Rapido White Bellflower
A Compact Mound of Upturned White Bells
Rapido White Bellflower (Campanula carpatica 'Rapido White') forms a tidy, low mound of bright green foliage covered in upward-facing, cup-shaped white bells from early summer on. Compact and quick to bloom, it's perfect for edging, rock gardens, and containers. A bee favorite that's deer-resistant and reliably hardy, it brings crisp, clean color to the front of sunny and part-shade borders in Edina, Woodbury, and Maple Grove.
