Showy Flowers
Canterbury bells is a charming flower that produces spectacular spikes of flowers with attached petals that resemble a saucer. Its blooms can be white, pink, blue, purple, or rose, and it makes a great cut flower. Stems arise from a rosette of slightly hairy, wavy-edged leaves. Growing between 2 and 4 feet tall, most varieties are perfect for the middle to rear or a garden. Canterbury bells have the greatest impact if planted in small groups. Smaller types can be used in containers and rock gardens.
