Genus of about 300 species of annuals, biennials, and perennials, some of which are evergreen. Campanula (The Italian Bellflower) is one of the best of all summer-flowering trailing plants. Excellent for containers and hanging baskets. The blooms are clustered at the tips of the stems, and one of the secrets of success for prolonging the display is to remove the flowers once they have faded. Campanula is an easy to grow plant. Once flowering is over, cut back the stems and keep cool and fairly dry during the winter rest period.
