<P> Phaseolus lunatus is of Andean and Mesoamerican origin . Two separate domestication events are believed to have occurred . The first, taking place in the Andes around 2000 BC, produced a large - seeded variety (lima type), while the second, taking place in Mesoamerica around 800 AD, produced a small - seeded variety (Sieva type). By around 1300, cultivation had spread north of the Rio Grande, and in the 1500s, the plant began to be cultivated in the Old World . </P> <P> The small - seeded (Sieva) type is found distributed from Mexico to Argentina, generally below 1,600 m (5,200 ft) above sea level, while the large - seeded wild form (lima type) is found distributed in the north of Peru, from 320 to 2,030 m (1,050 to 6,660 ft) above sea level . </P> <P> The Moche Culture (1--800 CE) cultivated lima beans heavily and often depicted them in their art . During the Spanish Viceroyalty of Peru, lima beans were exported to the rest of the Americas and Europe, and since the boxes of such goods had their place of origin labeled "Lima, Peru", the beans got named as such . Despite the origin of the name, when referring to the bean, the word "lima" is generally pronounced differently than the Peruvian capital . </P> <P> The term "butter bean" is widely used for a large, flat and yellow / white variety of lima bean (P. lunatus var . macrocarpus, or P. limensis). </P>
