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.
Hairy vetch is an annual or biannual viny legume with a woolly appearance due to long soft hairs borne on the stems and leaves. It remains green longer than the common vetch (Vicia sativa). It flowers and seeds late in the season and often survives the dry season, regenerating to almost full strength during the next rainy season. Vicia villosa has a scrambling and prostrate habit when young. It is 30-70 cm in height in mature swards. When it is provided with support for upright growth, hairy vetch may climb and reach a height of 1-2 m. Vicia villosa is appreciated as a cover crop and green manure.
