Common Noxious Weeds in Alberta – Creeping Bellflower

Creeping Bellflower (also known as Campanula rapunculoides) is a perennial weed that can reach up to 1 meter in height.

Perennial weeds grow from root stalks year after year. Perennial weeds spread by seeds and roots, and therefore the entire plant must be destroyed.

It is sometimes confused with the Bluebell/Harebell which is a similar species. To tell them apart, the bell-shaped flowers of the Bluebell/Harebell are smaller plus if you look along its stems you will find linear leaves, less than 1 cm wide.
