Plants in culture

Plants serve many functions in culture. The reliable provision of food through agriculture is the basis of civilization. The study of plant uses by native peoples is ethnobotany, while economic botany focuses on modern cultivated plants. Plants are used in medicine, providing many drugs from the earliest times to the present, and as the feedstock for many industrial products including timber and paper as well as a wide range of chemicals. Plants give millions of people pleasure through gardening.

In art, mythology, religion, literature and film, plants play important roles, symbolising themes such as fertility, growth, purity, and rebirth. In architecture and the decorative arts, plants provide many themes, such as Islamic arabesques and the acanthus forms carved on to classical Corinthian order column capitals.

Humans depend on plants for food, either directly or as feed for domestic animals. Agriculture deals with the production of food crops, and has played a key role in the history of world civilizations. Agriculture includes agronomy for arable crops, horticulture for vegetables and fruit, and forestry for timber. About 7,000 species of plant have been used for food, though most of today's food is derived from only 30 species. The major staples include cereals such as rice and wheat, starchy roots and tubers such as cassava and potato, and legumes such as peas and beans. Vegetable oils such as olive oil provide lipids, while fruit and vegetables contribute vitamins and minerals to the diet.
