Canterbury bells are biennials that produce only leaves the first season. Canterbury bells belong to the Campanulas family of plants, which consists of about 400 different species.
Canterbury bells grow as pyramid-shaped bushes that can reach 2 1/2 feet tall and from 12 to 15 inches wide. The bell-shaped flowers are about 2 inches long and come in pink, rose, lavender, blue or white.
Canterbury bells need full or partial sun and rich, moist soil. The seeds can be started indoors six to eight weeks before the last frost, or they can be directly sown in the garden when danger of frost has passed. Plant the seedlings outdoors 12 inches apart in an area protected from winds.
Give Canterbury bells fertilizer about once a month. When they get high, attach them to a stake to prevent them from falling over.
Because they are so tall, Canterbury bells can be used at the back of a garden or against a wall.
Canterbury bells can have problems with insects like slugs, snails, vine weevils, spider mites and aphids. Diseases include powdery mildew, rust, Septoria and Ramularia leaf spot, and southern blight.
