Variety already tested by sowing and the effect has been spectacular! The flowers make a beautiful impression in the flowerbeds and even come back the following year. Even if the mother plant dies afterwards, spontaneous sowings are then possible.

Description

Campanula medium or Canterbury Bells are a real cottage garden favourite. This sturdy, floriferous biennial is rather slow growing, but is well worth the wait! In spring and early summer, it displays large double bell-shaped blooms on erect stems in harmonious shades of white, pink, blue or purple. Grown en masse, it creates very romantic drifts of colour and is beautiful in flower arrangements. Grow in the sun or half-shade, in rich, cool, well-drained soil.

Campanula medium is a herbaceous plant of the Campanulaceae family, native to southern Europe. This seed mix brings together several double-flowered cultivars in various shades. In the first year, the plants form basal rosettes of lanceolate green leaves. The following year, from spring to early summer, strong 80 cm tall stems emerge, bearing large bell-shaped flowers (3 to 6 cm long). Colours range from white to pink, blue and purple. They are enclosed in large, prominent green chalices. Pollinated flowers give way to capsules, filled with small seeds that self-seed easily in the right conditions.

Canterbury Bells are without a doubt one of the prettiest bellflowers. They look marvellous in flower beds, borders, or dappled woodland scenes and adapt very well to seaside gardens. For a romantic effect, try combining them with late blooming tulips, peonies and old-fashioned roses. They can also be grown in large pots or containers and overwintered in the greenhouse.

Planting and care

Sow in late spring/early summer in well-prepared, rich, deep, loose soil. Sow in furrows, 6 mm deep, 15 cm apart. As soon as the seedlings are big enough to be handled (approximately 15 cm tall), transplant them to their definitive position. If possible, choose a shady spot. Add a good shovelful of compost in each planting hole. Space your plants 40 cm apart. Flowering will take place during the second year.

Remove spent flowers regularly for tidier plants and to encourage fresh blooms.
