Campanulas: A Guide to Growing Beautiful Bellflowers
What are Campanulas?
Campanulas are a diverse group of plants that includes both small, creeping species and towering perennials. They are known for their beautiful, usually blue, bell-shaped flowers that attract pollinators.
Growing Campanulas
Most campanulas grow best in moist but well-drained soil. They can tolerate a range of light conditions, from full sun to partial shade. Taller species may need to be staked to prevent them from flopping over.
Some popular campanulas include:
- Campanula rotundifolia: A creeping species that thrives in dry, nutrient-poor soils.
- Campanula portenschlagiana: A mat-forming perennial that is perfect for sunny or partially shaded spots.
- Campanula glomerata: A clump-forming species with clusters of brightly-colored flowers.
- Campanula latifolia: A tall, stately species with large, bell-shaped flowers.
- Campanula persicifolia: An old-fashioned cottage garden perennial with showy, bell-shaped flowers.
- Campanula lactiflora: A floriferous species with large heads of clustered flowers.
- Campanula poscharskyana: A trailing species that is well-suited to growing in crevices between paving tiles or stones.
- Campanula ‘Sarastro’: A hybrid with stunning midnight blue flowers.
- Campanula pyramidalis: A tall, dramatic species that is best grown from seed each year.
- Campanula carpatica: A popular alpine species with large, wide open flowers.
