ST. PAUL, MN (KDAL) - Another invasive species to keep track of is spreading into Minnesota. It's called the Oriental Bittersweet Vine and is commonly used for landscaping or holiday decorating. When it is established the vine can end up strangling trees, dominating forest canopies and kill smaller plants by lack of sunlight. It is illegal to transport or sell Oriental Bittersweet Vine in the state and if any is found, it should be destroyed immediately. Several of the nation's largest Oriental Bittersweet distributors are in Wisconsin which will make it easy for the invasive plant to move into Minnesota. Confirmed pockets of the vine have already been found growing in Red WIng, Stillwater, the Twin Cities and Winona areas.
