Campanula Medium Care
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.

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

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.
