Creeping bellflower spotted everywhere This pretty purple flower is actually a noxious weed

Letter to the Editor:

On many walks through my neighbourhood (Alberta Avenue), I see an abundance of the creeping bellflower plant, either in clumps in back alleys, or displayed with pride in people’s front yard gardens.

The City of Edmonton has designated this plant as a noxious weed.

In my own yard, I pull it out whenever I see it, but its growth patterns are such that, without using a toxic herbicide, it is almost impossible to get rid of. The roots grow deep and wide, so that just pulling the flower or the leaves doesn’t eliminate the plant. The foliage presents as ground cover and can quickly choke out other plants that we have chosen to plant. Letting the plant flower and seed ensures it will continue to propagate.

I don’t think anyone has any malicious intent, but they do need to be educated if we are going to continue to have residents who make an effort to have beautiful gardens and yards for the enjoyment of all.

This plant is a noxious weed, and the sooner we all become vigilant about pulling it out of our gardens, the better for us all.

Thanks so much,

Kieran Leblanc

Use the Alberta Weed Spotter app to identify and report noxious weeds or go to The city will remove weeds from public property. On private property, it’s the owner’s responsibility.

Tips from factsheet:

  • Pull, cut, or bag flower spikes before blooming to prevent seeds from producing.
  • Pull out the plant every 7 to 10 days to weaken the root system.
  • Dig out the root system.
  • Do not mow; the roots will grow thicker and lower.
  • No selective herbicides are registered to use on creeping bellflower.

  1. The yard I purchased 12 years ago contained quite a bit of this weed. I was unfamiliar with it the first year and did not get after it. Since then I have dug out roots whenever I was planting something new and I have found some roots as big as carrots. I feel like I am making progress; at a minimum I never let the flowers go to seed. Thanks for your post.

  2. I have found a quick method for eradicating creeping bellflower and it does not involve digging either. I’ve been fighting these things for MANY years and about 6 or 7 years ago I discovered a successful method to totally eradicate them. During successful field trials over those same 6 -7 years, I have eliminated them from lawns, flower beds and even growing right beside prized ornamentals – with no harm to the ornamentals. In my neighborhood, they are completely gone. If anyone wants more info, message me at
