Campanula medium, commonly known as Canterbury Bells, is a biennial plant in the family Campanulaceae. Native to southern Europe, it is known for its bell-shaped flowers that come in shades of blue, pink, and white. The plant typically grows in temperate climates and has a two-year life cycle, with the first year dedicated to vegetative growth and the second to flowering and seed production.
Campanula medium prefers moderate temperatures and bright, indirect light. It thrives in environments with moderate humidity and should be watered when the soil partially dries out. The plant can be grown both indoors and outdoors, making it versatile for various settings.
Soil
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil is rich in organic matter to support its growth. Good drainage is essential to prevent root rot.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and flowering.
Repotting
Repot Campanula medium when it outgrows its current container, typically every 1-2 years. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the early spring before the growing season begins.
Propagation
Propagate Campanula medium by seed. Sow seeds in late spring or early summer, and keep the soil moist until germination. Thin seedlings to allow enough space for growth. Alternatively, you can propagate by division in the spring.
Pruning
Prune the plant to remove spent flowers and encourage new growth. Cut back the stems after flowering to maintain a tidy appearance and promote a second bloom. Pruning is best done in late summer or early fall.
Toxicity
Campanula medium is not toxic to pets or humans, making it a safe choice for households with animals and children.
Additional
To encourage a longer blooming period, deadhead the flowers regularly. Mulching around the base of the plant can help retain soil moisture and regulate temperature. Protect the plant from extreme cold by providing a layer of mulch or moving it indoors during harsh winter months.
