Oriental Bittersweet
Infestation Winona 2012b - resize.jpgOriental Bittersweet, originally from Asia, is an invasive vine that can take over natural areas. The vine can smother and break off large tree branches. It also can kill trees by wrapping around trunks and girdling them. Because of the vine’s threat to the environment, the Minnesota Department of Agriculture (MDA) has added it to the state’s list of noxious weeds, with requirements to eradicate the plant where it’s found. There is a similar native species (American Bittersweet) which is not invasive so careful identification is needed.

Early detection and conrol of invasive species like Oriental Bittersweet can greatly reduce their long term impact. If you find Oriental Bittersweet on your property, save yourself a long term headache and start controlling it as soon as possible. For more information on control options, see the links at the bottom of the page.
