Seed Sowing:

The seeds of Campanula punctata ‘Cherry Bells’ are produced after the flowering period and can be harvested when they have turned brown. Once the seeds are collected, they can be sown in early spring or late summer.

The seedlings should be kept in a cold frame or under controlled conditions until they are large enough to be planted in the garden. Division:

Campanula punctata ‘Cherry Bells’ can also be propagated through division, which involves splitting a mature plant into smaller sections.

Replant the divided sections and water well. Stem Cuttings:

Stem cuttings are another way to propagate Campanula punctata ‘Cherry Bells.’ Cut a section of stem that is approximately 3-4 inches in length and remove any leaves from the lower section.

Dip the cut stem into rooting hormone and plant it into a pot filled with soil-less potting mix. Keep the soil moist and the cutting in a bright, warm, and humid location.

Once roots have formed, pot on into larger pots, before transplanting in the garden. Layering:

Finally, Campanula punctata ‘Cherry Bells’ can be propagated by layering, which is an asexual propagation method that involves bending a low-growing stem into the ground and covering it with soil until it roots.

While the plant can tolerate full sun, it flourishes best in dappled shade where temperatures are milder, and moisture levels are retained for longer. A steady drip through the growing season would be advantageous, although it never enjoys waterlogged conditions.

Campanula punctata ‘Cherry Bells’ is highly adaptable to many soil variations, including acidic, neutral, and alkaline soils, so that it can thrive in many different environments. Conclusion:

Campanula punctata ‘Cherry Bells’ is an adaptable and hardy plant that can be propagated through sexual or asexual means.

When planting Campanula punctata ‘Cherry Bells’ outdoors, partial shade to full sun is preferred, with about four to six hours of direct sunlight exposure daily. Shaded areas allow the soil to stay moist longer, while plants grown in full sun will establish well, and flower blooms will flourish.

The plant thrives in well-draining soils, which allow the roots to breathe and prevent it from developing root rot. Amend the soil with compost to provide additional nutrients to the plant.

It is best to plant this flower about 10-12 inches apart to prevent overcrowding, ensure maximum exposure to sunlight and provide adequate airflow surrounding the plant. This plant’s roots are shallow; therefore, mulch can help retain moisture and water quickly.

It is important, therefore, to ensure that the soil is kept adequately moist, and if it is exceptionally dry, watering twice weekly may be required. Giving the leaves an occasional spray of water can also keep the plant foliage fresh and keep pests away.


Campanula punctata is a versatile plant that can add beauty, vibrancy, and surprise to any home or outdoor space. This low maintenance plant can make a prolific food source for pollinators like hummingbirds, butterflies, and bees.
