Edible plants in the context of "List of edible cacti"

Human uses of plants include both practical uses, such as for food, clothing, and medicine, and symbolic uses, such as in art, mythology and literature. Materials derived from plants are collectively called plant products.

Edible plants have long been a source of nutrition for humans, and the reliable provision of food through agriculture and horticulture is the basis of civilization since the Neolithic Revolution. Medicinal herbs were and still remain to be the key ingredients of many traditional medicine practices, as well as being raw materials for some modern pharmaceuticals. The study of plant uses by native peoples is ethnobotany, while economic botany focuses on modern cultivated plants. Plants are also used as feedstock for many industrial products including timber, paper and textiles, as well as a wide range of chemicals.

The traditional kitchen garden, vegetable garden, also known as a potager (from the French jardin potager) or in Scotland a kailyaird, is a space separate from the rest of the residential garden – the ornamental plants and lawn areas. It is used for growing edible plants and often some medicinal plants, especially historically. The plants are grown for domestic use; though some seasonal surpluses are given away or sold, a commercial operation growing a variety of vegetables is more commonly termed a market garden (or a farm). The kitchen garden is different not only in its history, but also its functional design. It differs from an allotment in that a kitchen garden is on private land attached or very close to the dwelling. It is regarded as essential that the kitchen garden could be quickly accessed by the cook.

Historically, most small country gardens were probably mainly or entirely used as kitchen gardens, but in large country houses the kitchen garden was a segregated area, normally rectangular and enclosed by a wall or hedge, walls being useful for training fruit trees as well as offering shelter from wind. Such large examples very often included greenhouses and furnace-heated hothouses for more tender delicacies, and also flowers for display in the house; an orangery was the ultimate type. In large houses, the kitchen garden was typically placed diagonally to the rear and side of the house, not impeding the views from the front and rear facades, but still quick to access. In some cases, hardy flowers for cutting were grown outside there, rather than in the flower garden. A large country house hardly expected to buy any vegetables, herbs or fruit, and the surplus was often distributed as presents; the walled example at Croome Court in England covers seven acres, and the gardens have a large "Temple Greenhouse", an orangery in the form of a Roman Temple.
