Hairy Vetch

Vicia villosa, known as the hairy vetch, fodder vetch or winter vetch, is a plant native to some of Europe and western Asia. It is a legume, grown as a forage crop, fodder crop, cover crop, and green manure. Although non-native, it occurs in all US states and is considered invasive by some states, such as Alaska, Florida, Georgia, Michigan, Minnesota, Oregon, and Washington state — as well as in Japan and some parts of Europe where it is not native.[1][2][3][4][5][6][7][8][9] It is also found in most Canadian provinces.

Hairy vetch is very similar to tufted vetch (Vicia cracca), the most noticeable difference being that tufted vetch has a smooth stem.
