Lima beans ( Phaseolus lunatus )
The lima bean ( Phaseolus lunatus ), also moon bean called, is a plant of the genus Phaseolus in the subfamily of Schmetterlingsblütler (Faboideae). This crop is closely related to a number of other crops called " beans ". There is a large and a small-seeded subspecies, which are sometimes differentiated as Lima bean (large) and moon bean (small).
The Lima bean is native to the Andes and Central America . It is believed that cultivation began independently in the two places, in the Andes around 2000 BC. BC, where a large-seeded variety emerged (Lima type), and around 800 in Central America, where a small-seeded variety (Sieva type) emerged. By 1300 the cultivation had spread to the north of the Rio Grande .
It needs sufficient heat and can therefore only be cultivated economically to a limited extent in Central Europe.
The usually curved legumes are 5 to 15 centimeters long, 1.5 to 2.5 centimeters wide and contain two to four seeds. The seeds, which are very variable in shape, size and color, are 1 to 3 centimeters long, oval to round, and white or dark in color.
The number of chromosomes is 2n = 22.
