Super easy to grow. Canterbury Bells (Campanula medium) make a dramatic garden display. Handsome plants have large flowers and give a wonderful splash of colour early in the season. Flowers are white and shades of pink and purple.
Flowers are great for cutting, the strong stems look wonderful in arrangements.
It is important to note that Canterbury bells are biennials. This means that plants must to experience some cold to initiate flowering (note this is different to cold stratification of seeds whereby you only need to chill the seeds for germination purposes).
In the case of biennials, plants themselves need chilling by exposing them to the weather. Don’t molly coddle them in the warm. They will still grow, but they will fail to bloom until they are sure they have weathered a winter. A cold greenhouse or cold frame is ideal. H4 – Hardy through most of the UK (-10 to -5) give protection during a severe winter.
