Campanula carpatica is a dwarf, perennial campanula which forms low-growing floriferous mounds that slowly spread to form an attractive ground cover. Throughout summer the plants explode with cup-shaped, 5cm (2in), vivid blue or white blooms. The flowers are held on short stems above dainty heart shaped, bright green leaves.
Hardy to -34°C (-30°F), it is semi-evergreen to evergreen in warm winter climates. They are sun lovers and are easily grown in ordinary free draining soil. Deadheading will promote additional flowering.
Also known as bellflowers they work well in the front of the border, and are at home in the rock garden. They can be used as a groundcover in the mixed perennial border, are useful as a path edging and excellent in containers, hanging baskets and window boxes. The flowers are attractive to bees and can be used as cut flowers.
With their ease of production and showy displays, no wonder Campanula carpatica has become very popular in today’s landscapes.
- Awarded the RHS Award of Garden Merit
In 1993 Campanula carpatica was awarded the Royal Horticultural Society’s Award of Garden Merit (AGM).
A key indicator that this variety is worth growing in your garden.
Sow indoors in autumn to mid spring (Sept-March for flowering in April-August.)
Or sow in late spring (March to April) for flowering in July-August.
The species can also be grown from seed directly sown outdoors in autumn or after the last frost.
The seeds should be sown on the surface of the compost, press lightly into the compost but do not cover as they need light to germinate. The compost should be kept moist at all times.
Cover the seed container with a piece of glass or clear plastic and leave in a temperature of around 16-18°C (60-65°F) in a position which receives diffused light.
Germination between 14 and 28 days. Once some of the seeds have germinated air should be admitted gradually otherwise the seedlings may damp off.
When seedlings have their first pair of true leaves and are large enough to handle, transplant into 7.5cm (3in) pots to grow on in a coldframe. When large enough, plant out into their final position plant out 30-38cm (12-15in) apart. Avoid planting out seedlings until all threat of frost has passed.
Campanulas are easily grown in average, medium wet, well-drained soil in full sun to part shade. They require an average amount of water, as they do not tolerate really wet or overly dry conditions. Root zones that remain waterlogged tend to get root rot pathogens and can quickly lead to losses. Overly dry growing conditions greatly reduce quality and delay flowering. When watering is necessary, water plants thoroughly, and then allow the soil to dry slightly between waterings. During the growing season apply a balanced liquid fertiliser each month.
Deadheading spent blooms, though tedious, is easily done with a fingernail and will extend the bloom period. Campanulas can generally be grown free of insects and plant pathogens but slugs can damage tender new foliage,
In very hot summer climates Campanulas prefer part shade and will benefit from a summer mulch which helps keep root zone cool. Cut plants back to basal growth if foliage depreciates in summer.
Propagate Carpathian bellflower by dividing the clumps in spring or early summer.
Rock gardens, border fronts, path edging, Hanging baskets, window boxes, pots and containers.
The genus name campanula is derived from the Italian campana meaning 'bell' and refers to the shape of the flowers. The word is from Late Latin around 1630's, campana, originally meant 'a metal vessel made in Campania,' the region around Naples. All Campanulas have bell-shaped flowers, although the flower forms vary considerably.
The species name carpatica derives from Medieval Latin or Old Italian carpita the meaning has shifted over time. In the 13th century it originally meant a 'thick woolen cloth'. By mid-14c. it referred to a "tablecloth or bedspread;". By the 15c it meant floor coverings. The Old French carpite meaning "heavy decorated floor cloth', that we now would call carpets. It refers to the way the plant carpets the ground.
The common name Carpathian bellflower or Carpathian harebell is derived from their native origin, the Carpathian Mountains of Eastern Europe.
