About Canterbury-Bells

Campanula medium, the Canterbury bells, is a classic cottage garden biennial producing large, bell-shaped flowers in blue, pink, purple, and white. The flowers are perfectly bell-formed — wide at the base and narrowing at the top — giving the plant its association with church bells. Native to southern Europe, it grows 60–90 cm tall and blooms in late spring. The 'Cup and Saucer' variety has a flat calyx beneath each bell, creating a saucer effect. It self-seeds moderately, maintaining its presence in the garden. Canterbury bells have been grown in English gardens since the 16th century.

History

Illustrated historical scene for Canterbury-Bells

Campanula medium is native to southern France, northern Italy, and adjacent Mediterranean regions. It entered English gardens by the 16th century and is named for the bells worn by pilgrims traveling to the shrine of Thomas Becket at Canterbury Cathedral — the association traced to the plant's silvered bell-shaped flowers resembling the small horse and pilgrim bells common on the road. John Gerard described it in his 1597 Herball.

The distinctive "cup and saucer" or calycanthema form, with a secondary flared calyx mimicking a saucer beneath the bell, was selected in the 19th century and became a Victorian cottage-garden signature. As a biennial it flowers in its second year and then dies, requiring sequential sowing for continuous display. Canterbury bells remain a classic ingredient of English mixed borders and informal cottage plantings.

Canterbury bells are named after the small bells carried by pilgrims on their way to the shrine of Thomas Becket at Canterbury Cathedral in medieval England — the same pilgrimage immortalized in Chaucer's Canterbury Tales (1392). The flowers lined the pilgrimage routes through the English countryside. The genus Campanula (Latin for 'little bell') contains over 500 species, from tiny alpine rock plants to tall border perennials. Campanula medium was one of the first ornamental plants listed in early English gardening books, appearing in John Gerard's Herball (1597).

Symbolism & meaning

What It Symbolizes

Canterbury Bells take their name from the silver pilgrim-bells once tied to the saddles of those riding to Thomas Becket's shrine. Carried home by grateful pilgrims, the flower came to mean gratitude — a thank-you for safe return and prayers answered. Its stately stems of cupped bells still sound that medieval note of devotion, a gift to give when ordinary thanks feels too small.

  • Gratitude — Carried by grateful pilgrims, it represents thankfulness and spiritual devotion
