Phaseolus vulgaris

Phaseolus vulgaris, commonly known as the common bean, is a plant species in the legume family (Fabaceae). It is native to the Americas but has been introduced around the world. The species is economically important as a major source of protein and micronutrients.

Taxonomy

The Phaseolus vulgaris species was first described by Carl Linnaeus in his 1753 work Species Plantarum. The genus name Phaseolus comes from the Latin for "little boat", referring to the shape of the pods. The species name vulgaris means "common".

Description

Phaseolus vulgaris is an annual plant. It can grow to 2m in height, and the plants have a growth habit ranging from bushy (determinate) to climbing (indeterminate). The leaves are alternate, green, and trifoliate with ovate leaflets. The flowers are small, white or purple, and self-fertile, leading to the production of the beans.

Cultivation and uses

The Phaseolus vulgaris is cultivated worldwide for its edible beans, which can be harvested and consumed green (known as "snap beans") or allowed to mature and dry on the plant (known as "dry beans"). The beans are a staple food in many cultures and are a key source of protein.

Health benefits

Beans from Phaseolus vulgaris are rich in fiber and protein, and a good source of vitamins and minerals. They have been associated with various health benefits, including reducing the risk of heart disease and colorectal cancer, and helping to manage diabetes.
