Free Textbooks: A Meta Collection | Open CultureA botanical garden or botanic garden [nb 1] is a garden dedicated to the collection, cultivation , preservation and display of a wide range of plants labelled with their botanical names. It may contain specialist plant collections such as cacti and other succulent plants , herb gardens , plants from particular parts of the world, and so on; there may be greenhouses , shadehouses , again with special collections such as tropical plants , alpine plants , or other exotic plants. Visitor services at a botanical garden might include tours, educational displays, art exhibitions , book rooms, open-air theatrical and musical performances, and other entertainment. Botanical gardens are often run by universities or other scientific research organizations, and often have associated herbaria and research programmes in plant taxonomy or some other aspect of botanical science. In principle, their role is to maintain documented collections of living plants for the purposes of scientific research, conservation, display, and education, although this will depend on the resources available and the special interests pursued at each particular garden.
History of botany
The history of botany examines the human effort to understand life on Earth by tracing the historical development of the discipline of botany —that part of natural science dealing with organisms traditionally treated as plants. Rudimentary botanical science began with empirically-based plant lore passed from generation to generation in the oral traditions of paleolithic hunter-gatherers. The first written records of plants were made in the Neolithic Revolution about 10, years ago as writing was developed in the settled agricultural communities where plants and animals were first domesticated. The first writings that show human curiosity about plants themselves, rather than the uses that could be made of them, appears in the teachings of Aristotle's student Theophrastus at the Lyceum in ancient Athens in about BC; this is considered the starting point for modern botany. In Europe, this early botanical science was soon overshadowed by a medieval preoccupation with the medicinal properties of plants that lasted more than years. During this time, the medicinal works of classical antiquity were reproduced in manuscripts and books called herbals. In China and the Arab world, the Greco-Roman work on medicinal plants was preserved and extended.
