Canterburiklokje

Canterburiklokje, known in English as Canterbury bells, is a flowering plant in the Campanulaceae family. It is commonly cultivated as an ornamental garden plant and is native to southern Europe and parts of western Asia. The name reflects its traditional association with Canterbury, England, where the flowers have long been popular in cottage and formal borders.

Description and growth habit

Canterbury bells are typically described as biennials or short-lived perennials. They form a basal rosette in the first year and produce tall, erect stems in the second year, bearing large bell-shaped flowers. Plants usually reach 60–90 cm in height, sometimes taller with strong stems. Leaves are typically alternate, with basal leaves forming a rosette. Flowers are large, showy bells about 2–3 cm in diameter, arranged in terminal clusters. Colors include blue, violet, pink, and white, with many cultivars offering double forms.

Cultivation and care

They prefer cool climates and bloom in spring to early summer. Canterbury bells grow best in full sun to partial shade and in well-drained, fertile soil rich in organic matter. Regular moisture is important; avoid waterlogging and provide staking for tall stems. They are often grown as biennials, though some varieties can act as short-lived perennials in favorable conditions. Propagation is commonly via seeds sown indoors in late winter or directly outdoors after frost, with transplanting to the garden when seedlings are large enough.

Uses and varieties

Widely used in borders, cottage gardens, and as cut flowers, Canterbury bells offer a long-lasting display of color. They come in single and double flower forms, with a range of colors that suits diverse landscape designs.

Pests and diseases

Common issues include powdery mildew, rust, aphids, slugs, and occasionally root rot in poorly drained soils. Good air circulation, proper spacing, and well-drained soil help reduce problems.
