Canterbury bells, scientifically known as Campanula medium, are a beautiful addition to any garden with their vibrant bell-shaped flowers. However, it is important to note that Canterbury bells are biennial plants, which means they have a two-year life cycle. This means that they do not come back every year like perennial plants.
In the first year, Canterbury bells form a rosette of leaves close to the ground. These leaves help the plant build up energy reserves for the following year’s bloom. During this time, the plant focuses on establishing a strong root system.
In the second year, the Canterbury bells will send up tall, sturdy stems adorned with clusters of bell-shaped flowers. The flowers can come in various colors, including shades of blue, purple, pink, and white. The blooming period typically occurs in late spring or early summer, adding a burst of color to the garden.
After flowering, the plant will produce seed pods containing numerous tiny seeds. These seeds can be collected and saved for future planting if desired. However, as Canterbury bells are biennials, many gardeners choose to let the plant self-seed and produce new plants naturally.
It’s important to note that while the parent plant will die after flowering, the seeds it produces will drop to the ground and may germinate the following year. This means that new Canterbury bell plants may appear in your garden without any effort on your part. However, the timing and success of self-seeding can vary, depending on environmental conditions and other factors.
If you want to ensure a consistent display of Canterbury bells in your garden each year, it is recommended to sow new seeds annually. This way, you can have a continuous cycle of plants, with some growing and establishing roots in the first year, while others bloom in the second year.
To plant Canterbury bells, choose a sunny spot in your garden with well-draining soil. These plants prefer cool climates and may struggle in hot and humid regions. Prepare the soil by removing any weeds or rocks and incorporating organic matter to improve fertility and moisture retention.
Sow the seeds directly in the soil in early spring, as soon as the ground can be worked. Scatter the seeds lightly and cover them with a thin layer of fine soil. Keep the soil consistently moist but not waterlogged until the seeds germinate, which usually takes around 1-3 weeks. Once the seedlings have emerged, thin them to allow adequate spacing for proper growth.
As the plants grow, provide regular watering, especially during dry periods, to keep the soil evenly moist. Applying a balanced fertilizer once or twice during the growing season can help promote healthy growth and abundant blooms. Mulching around the base of the plants can also help conserve moisture and suppress weed growth.
While Canterbury bells are not perennial and do not come back every year, they can still be enjoyed in the garden through self-seeding or by sowing new seeds annually. With proper care and attention, these delightful biennial flowers will reward you with a burst of color and charm in your garden.
