Look for Canterbury bell seedlings at your local nursery in spring. Although seedlings are sometimes available, this flower is still somewhat unusual and is usually grown from seed.
Start seeds indoors 6 to 10 weeks before your region's last frost date.
Transplant outdoors in rich, well-drained soil that has plenty of compost or sphagnum peat moss worked in. Canterbury bells need a site in full sun to light shade.
Keep soil moist. Canterbury bells demand little care other than adequate moisture.
Consider fertilizing every two to three months during the growing season for best height and heaviest bloom.
Pull plants up after the first frost.
