Canterbury bells is a member of the bellflower family, so-called for the bell shape of the flowers. Members of the family typically have "bell" in their common names, such as harebell (Campanula rotundifolia).
The roots stay alive all winter underground. The second year, the rosette of leaves returns and the plants flower, produce seed and then die permanently after the first frost. The second year, when they grow more upright, the plants can be 18 – 36 inches feet tall and 9 – 16 inches wide.
Canterbury bells plant (Campanula medium) is a popular biennial (perennial in some areas) garden plant reaching about two feet (60 cm.) or slightly more. Campanula Canterbury bells can be easily grown and cared for much like their bellflower counterparts.. . . . .364011236204!]0000000000000009783314145012!]
