Commodities Affected:



Flowering Rush is a perennial plant from Europe and Asia that was introduced in the Midwest as an ornamental plant. It grows in shallow areas of lakes as an emergent, and as a submersed form in water up to 10 feet deep. Its dense stands crowd out native species like bulrush. The emergent form has pink, umbellate-shaped flowers, and is three feet tall with triangular-shaped stems. It has spread from a limited area around the Great Lakes and the St. Lawrence River to sporadically appear in the northern U.S. and southern Canada.



Flowering rush is known to occur in the Indiana county of Elkhart.
