For those in the Northerly and Easterly areas of this Country, who
have shade, with disturbed soil, Garlic Mustard is a real threat to
your garden or woodlot. A good description of this plant is he
http://ipaw.org/invaders/garlic_mustard/gm.htm, offered by the
Invasive Plant Association of Wisconsin.
Once it starts, it is extremely difficult to control. It takes over an
area fast, smothering native plants. hedgerows, or garden beds, and it
takes years to eradicate.
The little 4 petaled white flowers look cute, and you think that,
good, I got a free plant here. Just beware.
