Invasive - Eradicate!

Recently found in Wisconsin. Sacred Lotus is an exotic species most likely introduced in the United Sates by the aquarium industry. It is considered an aggressive and problematic plant in the U.S. because of the dense colonies which it forms. Sacred Lotus spreads by its rhizomes or seeds which have been documented to remain viable for over 1200 years! Please report new infestations to the DNR.
