Campanula- Canterbury Bell, Bell Flower

Profusely flowering garden plants, usually perennials, although some are grown as biennials.


Dwarf species belong to the category of rock plants and are intended for sunny to very lightly shaded spots. The medium-sized and tall species make excellent and reliable border plants, readily flowering and very suitable for combination with other plants.


The rock-plant species should not be kept too dry and require adequately nutritious soil. Provide good drainage in winter. Border plants will grow in reasonably manured garden soil which is never completely dry.


All pure species can be grown from seed; this may be done either in spring or in autumn. Biennials are sown in early summer. Garden varieities are increased by division or from cuttings taken in early spring.
