Species: P. vulgaris
The common bean (Phaseolus vulgaris) belongs to the Fabaceae family and is native to Central America. It was brought to Europe in around 1500, following the discovery of the New World, and later spread throughout all the climatic areas suitable for its cultivation. According to the variety, bean plants can be climbing, semi-erect or dwarf. The common bean, like all members of the Fabaceae family, is practically self-sufficient as far as nitrogenous nutrition is concerned; this is due to the symbiotic relationship with a bacterium that grows around the roots, and that is capable of fixing atmospheric nitrogen and making it available for the plant. Bean plants have a tap root from which secondary branch roots develop. The height of the stem may range from 40 cm – 50 cm, in dwarf varieties, to over 2 m in climbing ones. The leaves are compound, with three oval or heart shaped leaflets, while the flowers are grouped together and can be of various colours from white-yellow, to white-pink, to red-purple. The fruits, called pods or legumes, are hanging and can be of various shapes and sizes. The number of seeds they contain may vary according to the variety grown. When mature they can be white, yellow, green, reddish or variegated.
