Relatedly, another detail of usage is that several species of plants that are sometimes called beans, including ''Vigna angularis'' ( azuki bean), ''mungo'' ( black gram), ''radiata'' ( green gram), and ''aconitifolia'' ( moth bean), were once classified as ''Phaseolus'' but later reclassified—but the taxonomic revision does not entirely stop the use of well-established senses in general usage.

Maturity is typically 55–60 days from planting to harvest. As the bean pods mature, they turn yellow and dry up, and the beans inside change from green to their . As a , bean plants need external support, which may take the form of special "bean cages" or poles. Native Americans customarily grew them along with corn and squash (the so-called Three Sisters), with the tall acting as support for the beans.
In more recent times, the so-called "bush bean" has been developed which does not require support and has all its pods develop simultaneously (as opposed to pole beans which develop gradually). This makes the bush bean more practical for commercial production.

Five kinds of '' Phaseolus'' beans were domesticated by pre-Columbian peoples: common beans ('''') grown from Chile to the northern part of what is now the United States; and lima and sieva beans ('' P. lunatus''); as well as the less widely distributed teparies ('' P. acutifolius''), scarlet runner beans ('' P. coccineus''), and polyanthus beans.

(corn), and squash. The corn would not be planted in rows as is done by European agriculture, but in a checkerboard/hex fashion across a field, in separate patches of one to six stalks each.
Beans would be planted around the base of the developing stalks, and would vine their way up as the stalks grew. All American beans at that time were vine plants; "bush beans" were cultivated more recently. The cornstalks would work as a trellis for the bean plants, and the beans would provide much-needed nitrogen

Nitrogen is a nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the pnictogens. It is a common element in the ... for the corn. Squash would be planted in the spaces between the patches of corn in the field. They would be provided slight shelter from the sun by the corn, would shade the soil and reduce evaporation, and would deter many animals from attacking the corn and beans because their coarse, hairy vines and broad, stiff leaves are difficult or uncomfortable for animals such as deer and raccoons to walk through, crows to land on, and are a deterrent to other animals as well.
Beans were cultivated across Chile in Pre-Hispanic times, likely as far south as Chiloé Archipelago.
Dry beans come from both Old World varieties of broad beans (fava beans) and New World varieties (kidney, black, cranberry, pinto, navy/haricot).
Common genera and species
Currently, the world gene banks hold about 40,000 bean varieties, although only a fraction are mass-produced for regular consumption.
Most of the foods we call "beans", "legumes", "lentils" and "pulses" belong to the same family, ("leguminous" plants), but are from different genera and species, native to different homelands and distributed worldwide depending on their adaptability. Many varieties are eaten both fresh (the whole pod, and the immature beans may or may not inside) or shelled (immature seeds, mature and fresh seeds, or mature and dried seeds). Numerous legumes look similar, and have become naturalized in locations across the world, which often lead to similar names for different species.

Many types of bean like kidney bean contain significant amounts of antinutrients that inhibit some enzyme processes in the body. and phytates, present in grains, nuts, seeds and beans, interfere with bone growth and interrupt vitamin D metabolism. Pioneering work on the effect of phytic acid was done by Edward Mellanby from 1939.
Some kinds of raw beans contain a harmful, tasteless toxin: the lectin phytohaemagglutinin, which must be removed by cooking. Red kidney beans are particularly toxic, but other types also pose risks of food poisoning. Many types of beans contain lectins, and kidney beans have the highest concentrations – especially red kidney beans. As few as 4 or 5 raw beans can cause severe stomachache, vomiting and diarrhoea. A recommended method is to boil the beans for at least ten minutes; under-cooked beans may be more toxic than raw beans.
Cooking beans, without bringing them to a boil, in a slow cooker at a temperature well below boiling may not destroy toxins. A case of poisoning by butter beans used to make falafel

The production data for legumes are published by FAO in three categories:
# Pulses dry: all mature and dry seeds of leguminous plants except soybeans and groundnuts.
# Oil crops: soybeans and groundnuts.
# Fresh vegetable: immature green fresh fruits of leguminous plants.
The following is a summary of FAO data.
Main crops of "Pulses, Total (dry)" are "Beans, dry 76 26.83 million tons, "Peas, dry 87 14.36 million tons, "Chick peas 91 12.09 million tons, "Cow peas 95 6.99 million tons, "Lentils 01 6.32 million tons, "Pigeon peas 97 4.49 million tons, "Broad beans, horse beans 81 4.46 million tons. In general, the consumption of pulses per capita has been decreasing since 1961. Exceptions are lentils and cowpeas.
The world leader in production of dry beans ('' Phaseolus'' spp), is India, followed by Myanmar (Burma) and Brazil. In Africa, the most important producer is Tanzania.
