Overview

Campanula is a genus also known by the name Bellflower, because of its bell-shaped (sometimes tube- or star-shaped) flowers. Many species have become popular garden plants because they are easy to grow in a wide range of locations. While they prefer a sunny site, some Bellflowers are happy in partial shade. Most like the soil to be moist and they should never be allowed to dry out when in flower. Often blue, Campanulas can also be pink, purple or white. They can be spreading, clump-forming, trailing or upright in form, their leaves being oval or lance-shaped. Some are evergreen. There are over 400 annual, biennial and perennial species of Campanula which range greatly in size and preferred habitat, and are distributed across temperate and subtropical environments in the Northern Hemisphere. Scotland and Ireland term this genus Bluebell. However, it is not related to the true bluebell, Hyacinthoides non-scripta.

Common problems

Harvesting

Deadheading the plants regularly will encourage more blooms to develop. Keep the seed heads in paper bags until ready to sow.

Propagation

Cuttings

Basal cuttings in spring.

Division

Division best done in spring or autumn.

Seed

Sow seed directly into the garden in late spring or early summer with only a thin layer of soil covering them. Keep moist, and thin out or replant once the seedlings become large enough.
