The Campanula or Bellflower is an easy-to-grow, ground-covering, winter-hardy plant. It comes in a variety of colours, including blue, purple, and pink. Because of their distinctive bell-shaped, upturned flowers, Campanulas have been called Bellflowers.

How to Grow Campanula or Bellflower

It is important to learn everything you can about growing and caring for Campanula flowers if you are ready to plant them in your yard.

Soil and Mulch

Plant in well-drained soil that can withstand partial to full sunlight. Campanula will produce more flowers the more sunlight it receives.

After planting your Campanula, add 2-3 inches of organic mulch to the area. Please avoid mulching directly against the plant as this can cause possible rot. The mulch will retain moisture and prevent weeds from growing in your garden. It can also fertilize your gardens as it breaks down.


Space the plants 15-18 inches apart for planting. These flowers can be very sprawling so it is best to divide them in spring and fall. You can either cut down your Campanula once winter arrives or leave it as overwintering habitat for birds.

Its Blooms

Campanulas bloom for a long time, and their best colours are seen from late spring through early fall. These flowers require very little maintenance. You can water them during dry spells and fertilize them once a year with an all-purpose garden food (5-10-10 or 10-10).

To encourage more blooms, trim dead heads and extend the flowering period. To prevent damage to your flower stems, always use small scissors or gardening tools when trimming Campanula.
