Plant Common Name

Canterbury Bells

General Description

Campanula medium, commonly called Canterbury bells, is a short-lived herbaceous perennial that originates from western Europe. In late spring to early summer, clumps of medium green basal foliage put forth tall leafy stems lined with large cup-shaped bells of blue, purple, white, or pink. There are many cultivars to include members of the floriferous Champion Series, which may have blue, pink or white flowers. Likewise, the distinctive flowers of the popular variety calycanthema look like floral cups sitting on broad petaled saucers. Once flowers are spent, plants will not rebloom. Canterbury bells prefer sites with full to part sun and fertile, well drained soil. Lovely and old-fashioned, they are well-suited to perennial borders and cottage gardens.
