Overview of Campanula carpatica
Campanula is a large genus of about 300 species, all native to temperate regions of the Northern Hemisphere. There are annual, biennial, and perennial types within the genus.
Campanula carpatica is a low growing, hardy perennial species that originates from the Carpathian Mountains of southeastern Europe. Carpathian bellflower, Carpathian harebell, or tussock bellflower are all common names for this species.
Carpathian bellflower is hardy to zone 3a.
The plant forms a neat mound of light green foliage about a foot wide and 6 to 8 inches tall. Unlike some Campanula species, C. carpatica is not an aggressive runner and remains as a compact clump. The small, smooth-textured, heart shaped, slightly toothed leaves emerge in spring, and by mid-summer upturned, cup-shaped flowers 1 to 2 inches wide are produced on thin, wiry stems held above the leaves. Plants bloom for several weeks, producing numerous flowers on each plant. A sparse re-bloom sometimes continues throughout the summer to early fall in cool summer climates.
Landscape Use of Campanula carpatica
Grow C. carpatica in full sun to partial shade in fertile, well-drained soil, spacing plants 12 to 14 inches apart. The plants grow best with cool soil, so mulch the plants and provide adequate moisture during dry weather. This plant works well in the front of the border and is also at home in the rock garden. It can be used as a groundcover in the mixed perennial border or even in containers or as an indoor flowering plant. The flowers are attractive to pollinators and can be used as cut flowers. Deadhead to promote additional flowering.
C. carpatica has few pests, but slugs can damage tender new foliage, and fungal pathogens occasionally attack the leaves.
Propagating Campanula carpatica
Carpathian bellflower can easily be grown from seed by sowing indoors 7 to 9 weeks before the last expected spring frost. Cover the small seed only lightly, as light is beneficial for germination, and maintain temperatures between 68 to 72 °F.
Established plants can be propagated by dividing them in spring or early summer.
Varieties of Campanula carpatica
Several varieties of C. carpatica are available. These include:
- ‘Clips’ series is a popular seed propagated series that features the colors Blue, Deep Blue, White, and a mix of these colors. Plants grow about 8 inches tall.
- ‘Pearl’ series is an early-blooming, seed propagated series available in both Deep Blue and White.
- ‘Pristar’ series features large flowers on early-blooming plants that grow 8 to 12 inches tall. Reportedly the earliest flowering series available. Seed propagated.
- ‘Rapido’ series is a very early-blooming, seed propagated series (flowering about a month before ‘Clips’ varieties) with good vigor and compact habit. Grows 5 to 7 inches tall.
