How Tall Do Canterbury Bells Grow?

Canterbury Bells feature long flower stalks and bell-shaped flowers. It’s a biennial, which means they bloom during their second year.

The flower stalks can reach up to three feet tall and sprout from a rosette of green leaves.

Due to their height, these Campanula plants are usually grown outdoors. In fact, you may struggle to keep plants alive if you decide to try caring for them indoors.

While it may not thrive inside, it is an easy plant to care for outdoors. The stalks should appear during the second year and may form as a single stalk or a branched stalk.

Canterbury Flowering and Fragrance

After the stalks rise, you may see the buds forming on the tips. In the early summer, the flowers should open to reveal their bell-shaped appearance.

In some cases, the flowers bloom in late spring and last through the early fall.

The blooms also last a long time when cut, making them a great choice for adding to a vase or bouquet.

Unfortunately, the lovely white bell flowers don’t produce a scent.

What Lighting Conditions Does Campanula Grow Best?

Canterbury bell plants grow best when positioned in a bright area with full sun. Growing in partial shade produces weak stems. Again, you shouldn’t try to grow them indoors. Place them in pots or containers you keep outdoors.

The plant is listed for USDA hardiness zones 4 through 10, which covers many zones. But, the Campanula medium prefers cooler temperatures.

In the winter, you may need to cover the plant with a cold frame.

NOTE: A cold frame is an enclosure for plants with transparent panels. The panels allow sunlight while shielding the plant from snow and severe weather.

Watering and Feeding

Water Campanula plants throughout the summer, to keep the soil moist. If you touch the soil and it feels dry, it needs water.

Make sure to avoid keeping the soil soaked.

Fertilize plants using a water-soluble liquid fertilizer every two weeks during the summer. Stop feeding when the flowers start to wilt.

Soil and Transplanting

The Canterbury Bells Campanula grows well in regular potting soil without any additional amendments. However, if you are growing from seed, you may want to add a little sand to the mix.

Canterbury plants need a well-drained soil whether the plant grows in the ground or a container.

When repotting, try to do so in the early spring, just before the weather starts to warm up.

Deadheading, Grooming, and Maintenance

Throughout the blooming season, deadhead and remove any withered flowers. This helps prolong the blooming.

New flowers will regularly replace the dead ones, but only if you remove them.

How To Propagate Canterbury Bells

Propagate by flower seeds by allowing the plant to go to seed after it stops flowering.

Sow seeds in the summer and allow the plants to sit throughout the winter. In the spring, plant the Canterbury Bells to grow on in your garden or in containers.

Pests or Disease Problems On Medium Campanula

Campanula plants are easy to care for and rarely affected by diseases. As the flowers don’t produce a scent, insects and other pets tend to leave the plant alone.

If you do detect aphids, wash them away with sprays of cold water. While these infestations are rare, check the plant often for pests.

As mentioned, the Canterbury Bells plant is robust outdoors..

When growing indoors, you may need to deal with the whitefly, which can be controlled with an insecticide or organic Neem oil.
