Wildflower
Field notes: Canada Thistle has beautiful flowers, but the
plant is a major pest out competing many native plants. Every
effort should be made to keep the plants from flowering and going
to seed. Some control can be gained by digging the large tap
roots. Removing flower heads before Canada Thistle goes to seed
will help to prevent further spreading. Spraying with a herbicide
such as Roundup offers the best control.
