It is a vine-like annual plant that is widely cultivated for forage and as a cover crop in agricultural systems.

Sweet vetch typically grows to approximately 1 to 2 meters in height, with slender stems that branch out and tend to twine or climb upon support. The leaves of this plant are composed of several pairs of oblong or lanceolate leaflets, giving it a pinnate appearance. The foliage is usually a dull green color, providing a lush and deep texture.
When in bloom, sweet vetch produces numerous clusters of attractive flowers on the tips of its stems. These flowers range in color from lavender to purple and occasionally pink. Each flower is composed of a standard petal, two wing petals, and a keel, which encloses the reproductive organs. The blossoms are not only visually appealing but also highly attractive to various pollinators.
In terms of its benefits in agriculture, sweet vetch is valued for its ability to fix nitrogen in the soil through symbiotic relationships with nitrogen-fixing bacteria present in its root nodules. This makes it an effective cover crop for improving soil fertility and structure. Additionally, sweet vetch is often used as a forage crop, offering valuable feed for livestock due to its relatively high protein content and palatability.
Overall, sweet vetch is a versatile and beneficial plant, valued both for its agricultural contributions and its aesthetic qualities.
