Noxious weeds are plant species designated in the Alberta Weed Control Act. Noxious weeds must be controlled, meaning their growth or spread needs to be prevented.
Creeping bellflower is native to Europe and was introduced to North America as an ornamental flower.
Creeping bellflower can be an aggressive invader in natural plant communities. It can survive droughts and survive in a wide range of light conditions. This plant’s thick creeping roots can travel under fences, lawns, and concrete, making it very difficult to control. This plant is also resistant to many chemicals.
The flowers are purple, blue or sometimes white, bell-shaped, and nodding. Each plant has numerous flowers that are arranged on one side of the stem. The heart shaped leaves are 2-5 cm wide, have toothed edges, and are alternately arranged along the stem.
The plant grows up to 100 cm tall and has a creeping root (rhizome) which gives this plant its name. Plants reproduce by seeds and by the rhizomes and can re-generate from very small root pieces in the soil.
Can Be Confused With...
Native harebells - Campanula species - creeping bellflower has much taller stems, larger flowers and leaves, and leaf shape.
Clustered Bellflower - Campanula glomerata - which is an ornamental garden plant and fine for you to grow!
