Canterbury Bells (Campanula medium) is a stately biennial of the bellflower family (Campanulaceae), native to southern Europe. In its second year it sends up leafy stems 60-100 cm tall, hung in early summer with large, cup-and-saucer bells of blue, purple, pink or white. A long-established cottage-garden flower, it is valued for borders and as a cut flower.
Science & Biotechnology
Within the Campanula group, Campanula medium is of continuing interest to researchers working on plant diversity, seed biology and the selection of improved garden forms. Its strict two-year biennial cycle has also made it a useful teaching example in horticultural education illustrating biennial plant life cycles. Little about its garden performance is mysterious; it has been grown and observed for a very long time.
Uses & Benefits
In the garden, Canterbury Bells earns its place in borders, containers and mixed plantings, and it also rewards growers who raise plants for cutting, drying or kitchen use. Canterbury bells is a beloved traditional cottage garden biennial, its tall, dramatic flower spikes providing genuine old-fashioned charm and excellent cut-flower value in early summer of its second year. As with all true biennials, patience through the first year of foliage-only growth is part of successfully growing this classic garden flower. Given the right start, it carries on with minimal intervention.
Bellflowers include rampion, once grown as a salad vegetable, and the East Asian balloon-flower relatives with medicinal roots; most garden campanulas are simply beautiful perennials for the border.
Growing from Seed
Raising Canterbury Bells from seed is straightforward. Sow seed onto surface of a loose, well-drained mix without covering it deeply, since light supports germination, and keep it consistently moist. Full sun to light shade suits this classic biennial well, and remember that flowering occurs only in the plant’s second year, so patience through the first season is essential. A simple routine works well: sow evenly over the surface and cover lightly in a loose, well-drained seed compost, maintain even moisture, and provide full sun. Prick the seedlings out once they are large enough to handle, grow them on in bright light, and plant out when conditions allow.
Our Take
Canterbury Bells has real presence in the garden without demanding much in return. Canterbury Bells is the kind of plant that rewards a permanent spot. Attention to moisture in the first weeks pays off; later, the plant is forgiving.
