Flowering Rush is a prohibited, noxious weed that has been introduced into several Alberta water bodies. It is an aquatic plant that grows as an emergent plant along shorelines of both lakes and rivers. Flowering Rush was brought to North America from Europe as a garden plant. This variety will form dense stands which will interfere with recreational lake use. Flowering Rush crowds out our native plants and has the potential to fill in an entire lake if left uncontrolled.
