Illinois Adds Brazilian Elodea and Eurasian Watermilfoil to List of Banned Plants
The Illinois Department of Natural Resources recently banned the sale of 27 new aquatic plants. The plants were added to its Injurious Species List, which also made it illegal to gift, barter, exchange, loan, or transport the plants without a permit. Plants on this list include flowering rush (Butomus umbellatus), Brazilian elodea (Egeria densa), yellow flag iris (Iris pseudacorus), and Eurasian watermilfoil (Myriophyllum spicatum).

Plant species were chosen based on the results of a risk assessment tool, which evaluates species based on factors like ability to thrive in the Great Lakes and difficulty to control.

One of the most high risk species on both lists is the aquatic superweed Hydrilla verticillata. Hydrilla has not yet arrived in Illinois, but has already been found in Indiana, Wisconsin, Kentucky, and Tennessee. At one time Hydrilla invasions in the northern U.S. were considered unlikely because of colder temperatures, but a new biotype has been invading and overwintering in several northern states.
