Vetch is a type of flowering plant belonging to the legume family, known scientifically as Fabaceae. It is commonly found in temperate regions and is characterized by its climbing or trailing growth habit. Vetch plants produce small, pea-like flowers and are often used as cover crops to improve soil health by fixing nitrogen. There are several species of vetch, with common vetch and hairy vetch being the most widely recognized. These plants are beneficial for agriculture, as they help prevent soil erosion and provide forage for livestock. Additionally, vetch can enhance biodiversity by attracting various pollinators.
