Scentless Chamomile is a noxious weed spreading across Alberta, especially in disturbed areas like roadsides, fields, and pastures. Early detection is key!

Why it’s considered noxious:

  • Aggressively outcompetes native plants and crops

  • Can produce thousands of seeds per plant, spreading rapidly
  • Difficult to control once established
