The history of botanical gardens is closely linked to the history of
botany itself. The botanical gardens of the 16th and 17th centuries were medicinal gardens, but the idea of a botanical garden changed to encompass displays of the beautiful, strange, new, and sometimes economically important plant trophies being returned from the European colonies and other distant lands. In the 18th century, they became more educational in function, demonstrating the latest plant classification systems devised by botanists working in the associated herbaria as they tried to order these new treasures. Then, in the 19th and 20th centuries, the trend was towards a combination of specialist and eclectic collections demonstrating aspects of both horticulture and botany.
Precursors The idea of "scientific" gardens used specifically for the study of plants dates back to antiquity. The origin of modern botanical gardens is generally traced to the appointment of botany professors to the medical faculties of universities in 16th-century Renaissance Italy, which entailed curating a medicinal garden. However, the objectives, content, and audience of today's botanic gardens more closely resemble that of the grandiose gardens of antiquity and the educational garden of
Theophrastus in the Lyceum of ancient Athens.

Martin Heemskerck Near-Eastern royal gardens, set aside for economic use or display and containing at least some plants gained by special collecting trips or military campaigns abroad, are known from the second millennium BCE in
ancient Egypt,
Mesopotamia,
Crete,
Mexico and
China. In about 2800 BCE, the Chinese Emperor
Shen Nung sent collectors to distant regions searching for plants with economic or medicinal value. It has also been suggested that the
Spanish colonization of Mesoamerica influenced the history of the botanical garden. as well as gardens in
Chalco (altépetl) and elsewhere, greatly impressed the Spanish invaders, not only with their appearance, but also because the indigenous
Aztecs employed many more medicinal plants than did the classical world of Europe. Early medieval gardens in
Islamic Spain resembled later botanic gardens, an example being the 11th-century Huerta del Rey garden of physician and author
Ibn Wafid (999–1075 CE) in
Toledo. This was taken over by garden chronicler
Ibn Bassal (fl. 1085 CE) until the Christian conquest in 1085 CE. Ibn Bassal then founded a garden in Seville, most of its plants being collected on a botanical expedition that included Morocco, Persia, Sicily, and Egypt. The medical school of
Montpellier was also founded by Spanish Arab physicians, and by 1250 CE, it included a physic garden, but the site was not given botanic garden status until 1593.
Physic gardens Botanical gardens developed from
physic gardens, whose main purpose was to cultivate
herbs for medical use as well as research and experimentation. Such gardens have a long history. In Europe, for example,
Aristotle (384 BCE – 322 BCE) is said to have had a physic garden in the
Lyceum at Athens, which was used for educational purposes and for the study of botany. This was inherited, or possibly set up, by his pupil
Theophrastus, the "Father of Botany". There is some debate among science historians whether this garden was ordered and scientific enough to be considered "botanical"; instead, they attribute the earliest known botanical garden in Europe to the botanist and
pharmacologist Antonius Castor, mentioned by
Pliny the Elder in the 1st century. The forerunners of modern botanical gardens are generally regarded as being the medieval monastic physic gardens that originated after the decline of the
Roman Empire at the time of Emperor
Charlemagne (742–789 CE). These contained a , a garden used mostly for vegetables, and another section set aside for specially labelled medicinal plants; this was called the or —more generally known as a physic garden—and a or orchard. Such gardens were given impetus by Charlemagne's
Capitulary de Villis, which listed 73 herbs to be used in the physic gardens of his dominions. Many of these had already been introduced to British gardens.
Pope Nicholas V set aside part of the Vatican grounds in 1447 for a garden of medicinal plants that were used to promote the teaching of botany, and this was a forerunner to the University gardens at Padua and Pisa established in the 1540s. Certainly, the founding of many early botanic gardens was instigated by members of the medical profession.
16th- and 17th-century European gardens —the oldest academic botanic garden still at its original location In the 17th century, botanical gardens began their contribution to a deeper scientific curiosity about plants. If a botanical garden is defined by its scientific or academic connection, then the first true botanical gardens were established with the revival of learning that occurred in the European
Renaissance. These were secular gardens attached to universities and medical schools, used as resources for teaching and research. The superintendents of these gardens were often professors of botany with international reputations, a factor that probably contributed to the creation of botany as an independent discipline rather than a descriptive adjunct to medicine.
Origins in the Italian Renaissance The botanical gardens of
Southern Europe were associated with university faculties of medicine and were founded in
Italy at
Orto botanico di Pisa (1544),
Orto botanico di Padova (1545),
Orto Botanico di Firenze (1545),
Orto Botanico dell'Università di Pavia (1558) and
Orto Botanico dell'Università di Bologna (1568). Here the physicians (known in English as
apothecaries) delivered lectures on the Mediterranean "simples" or "
officinals" that were being cultivated in the grounds. Student education was no doubt stimulated by the relatively recent advent of printing and the publication of the first herbals.
Northern Europe The tradition of these Italian gardens spread across Europe, with early examples including: •
Leipzig Botanical Garden, Germany (1543) •
Botanical Garden of Valencia,
Spain (1567) •
Hortus Botanicus Leiden, Netherlands (1590) •
Jardin des plantes de Montpellier, France (1593) •
University of Copenhagen Botanical Garden, Denmark (1600) •
University of Oxford Botanic Garden, England (1621) •
Jardin des Plantes, Paris (1635) •
Hortus Botanicus (Amsterdam), Netherlands (1638) •
Uppsala University, Sweden (1655) •
Chelsea Physic Garden, England (1673) •
Royal Botanic Garden Edinburgh, Scotland (1670)
Beginnings of botanical science was established in 1673. During the 16th and 17th centuries, the first plants were being imported to these major
Western European gardens from
Eastern Europe and nearby
Asia (which provided many
bulbs), and these found a place in the new gardens, where they could be conveniently studied by the plant experts of the day. For example, Asian introductions were described by
Carolus Clusius (1526–1609), who was director, in turn, of the
Botanical Garden of the University of Vienna and
Hortus Botanicus Leiden. Many plants were being collected from the
Near East, especially bulbous plants from
Turkey. Clusius laid the foundations of
Dutch tulip breeding and the bulb industry, and he helped create one of the earliest formal botanical gardens of Europe at
Leyden where his detailed planting lists have made it possible to recreate this garden near its original site. The of Leyden in 1601 was a perfect square divided into quarters for the four continents, but by 1720, though, it was a rambling system of beds, struggling to contain the novelties rushing in, and it became better known as the . His
Exoticorum libri decem (1605) is an important survey of exotic plants and animals that is still consulted today. In the mid to late 17th century, the Paris
Jardin des Plantes was a centre of interest with the greatest number of new introductions to attract the public. In
England, the
Chelsea Physic Garden was founded in 1673 as the "Garden of the Society of Apothecaries". The Chelsea garden had heated
greenhouses, and in 1723 appointed
Philip Miller (1691–1771) as
head gardener. He had a wide influence on both botany and horticulture, as plants poured into it from around the world. The garden's golden age came in the 18th century, when it became the world's most richly stocked botanical garden. Its seed-exchange programme was established in 1682 and still continues today.
18th century Gardens and orangeries was designed by F. Argounov. With the increase in
maritime trade, ever more plants were brought back to Europe as trophies from distant lands, and these were triumphantly displayed in the private estates of the wealthy, in commercial
nurseries, and in the public botanical gardens. Heated conservatories called "
orangeries" became a feature of many botanical gardens. , built 1844–1848 by
Richard Turner to
Decimus Burton's designs.
Kew Gardens, London, established 1759. The
Royal Botanic Gardens, Kew, was founded in 1759, initially as part of the Royal Garden set aside as a physic garden.
William Aiton (1741–1793), the first curator, was taught by garden chronicler
Philip Miller of the Chelsea Physic Garden, whose son Charles became the first curator of the original
Cambridge Botanic Garden (1762). In 1759, the "Physick Garden" was planted, and by 1767, it was claimed that "the Exotick Garden is by far the richest in Europe". Gardens such as the Royal Botanic Gardens, Kew (1759), the
Orotava Acclimatization Garden in
Tenerife (1788), and the
Real Jardín Botánico de Madrid (1755) were set up to cultivate new species returned from expeditions to the tropics; they also helped found new tropical botanical gardens. From the 1770s, following the example of the
French and
Spanish, amateur collectors were supplemented by official horticultural and botanical plant hunters. These botanical gardens were boosted by the flora being sent back to Europe from various European
colonies around the globe. At this time, British horticulturalists were importing many
woody plants from
Britain's colonies in North America, and the popularity of horticulture had increased enormously, encouraged by the horticultural and botanical collecting expeditions overseas fostered by the directorship of
Sir William Jackson Hooker and his keen interest in
economic botany. At the end of the 18th century, Kew, under the directorship of Sir
Joseph Banks, enjoyed a golden age of plant hunting, sending out collectors to the
South African Cape,
Australia,
Chile,
China,
Ceylon,
Brazil, and elsewhere, and acting as "the great botanical exchange house of the
British Empire". From its earliest days to the present, Kew has in many ways exemplified botanic garden ideals, and is respected worldwide for the published work of its scientists, the education of horticultural students, its public programmes, and the scientific underpinning of its horticulture. In 1728,
John Bartram founded
Bartram's Garden in
Philadelphia, one of the continent's first botanical gardens. The garden is now managed as a historical site that includes a few original and many modern specimens as well as extensive archives and restored historical farm buildings.
Plant classification The large number of plants needing description were listed in garden catalogues; and from 1753
Carl Linnaeus established the system of
binomial nomenclature which greatly facilitated the listing process. Names of plants were authenticated by dried plant specimens mounted on card (a or garden of dried plants) that were stored in buildings called
herbaria. These
taxonomic research institutions were frequently associated with the botanical gardens, many of which by then had "order beds" to display the classification systems being developed by botanists in the gardens' museums and herbaria. Botanical gardens became scientific collections, as
botanists published their descriptions of the new exotic plants, and these were recorded for posterity in detail by superb botanical illustrations. Botanical gardens effectively dropped their medicinal function in favour of scientific and aesthetic priorities, and the term "botanic garden" came to be more closely associated with the herbarium, library, and laboratories housed there than with the living collections—on which little research was undertaken.
19th century ,
Jardin des Plantes, built 1834–1836 by
Charles Rohault de Fleury. Example of French glass and metal architecture. The late 18th and early 19th centuries were marked by the establishment of tropical botanical gardens as a tool of
colonial expansion (for trade and commerce and, secondarily, science) mainly by the British and Dutch, in
India,
South-east Asia, and the
Caribbean. This was also the time of Sir
Joseph Banks's botanical collections during Captain
James Cook's
circumnavigations of the planet and his explorations of
Oceania, with plant introductions on a grand scale.
Tropical There are currently about 230 tropical botanical gardens, many of them in southern and south-eastern Asia. The first botanical garden founded in the tropics was the
Pamplemousses Botanical Garden in
Mauritius, established in 1735 to provide food for ships using the port, but later trialling and distributing many plants of economic importance. This was followed by the
West Indies (
Saint Vincent and the Grenadines Botanic Gardens, 1764) and in 1786 by the
Acharya Jagadish Chandra Bose Botanical Garden in
Calcutta, India, founded during a period of prosperity when the city was a trading centre for the
Dutch East India Company. Other gardens were constructed in
Brazil (
Rio de Janeiro Botanical Garden, 1808),
Sri Lanka (
Botanic Gardens of Peradeniya, 1821, on a site dating back to 1371),
Indonesia (
Bogor Botanical Gardens, 1817 and
Kebun Raya Cibodas, 1852), and
Singapore (
Singapore Botanical Gardens, 1822). These had a profound effect on the economy of the countries, especially in relation to the foods and medicines introduced. The importation of
rubber trees to the Singapore Botanic Garden initiated the important rubber industry of the
Malay Peninsula. At this time also,
teak and
tea were introduced to India, and
breadfruit,
pepper, and
starfruit to the Caribbean. Included in the charter of these gardens was the investigation of the local
flora for its economic potential to both the colonists and the local people. Many crop plants were introduced by or through these gardens—often in association with European botanical gardens such as Kew or Amsterdam—and included
cloves,
tea,
coffee, breadfruit,
cinchona,
sugar,
cotton,
palm oil, and
Theobroma cacao (for chocolate). Especially in the tropics, the larger gardens were frequently associated with a herbarium and museum of economy. The Botanical Garden of Peradeniya had considerable influence on the development of agriculture in
Ceylon where the
Para rubber tree () was introduced from Kew, which had itself imported the plant from
South America. The transfer of
germplasm between the temperate and tropical botanical gardens was undoubtedly responsible for the range of agricultural crops currently used in several regions of the tropics.
Temperate , with native
protea flowers in the foreground, and Castle Rock in the background The first botanical gardens in
Australia were founded early in the 19th century: the
Royal Botanic Gardens, Sydney, 1816; the
Royal Tasmanian Botanical Gardens, 1818; the
Royal Botanic Gardens, Melbourne, 1845;
Adelaide Botanic Gardens, 1854; and
Brisbane Botanic Gardens, 1855. These were established essentially as
colonial gardens of economic botany and acclimatisation. South Africa has 10 national botanical gardens, all overseen by the
South African National Biodiversity Institute. The oldest in South Africa is the 1851
Durban Botanic Gardens. The
Kirstenbosch National Botanical Garden is the most famous and developed garden in the country, established in 1913 on a site dating to 1848. It covers 36
hectares, with an additional 528 hectares of mountainside wilderness forming part of the garden.
Stellenbosch University Botanical Garden is South Africa's oldest university botanical garden; it was established in 1922. Also in the country is the
Karoo Desert National Botanical Garden, founded in 1921 and relocated in 1945. Elsewhere in Africa,
Orman Garden at
Giza in
Egypt was founded in 1875. of the
Saint Petersburg Botanical Garden, founded in 1714 Presidents
George Washington,
Thomas Jefferson, and
James Madison, all experienced farmers, shared the dream of a national botanic garden, leading to the founding in 1820 of the
United States Botanic Garden, next to the
Capitol in
Washington DC. In 1859, the
Missouri Botanical Garden was founded at
St Louis, Missouri; it is one of the world's leading gardens specializing in tropical plants. and the
Saint Petersburg Botanical Garden, (1714).
20th century ,
Aswan, Egypt , with a view of the
zig-zag bridge Civic and municipal botanical gardens A large number of civic or municipal botanical gardens were founded in the 19th and 20th centuries. These did not develop scientific facilities or programmes, but the horticultural aspects were strong and the plants often labelled. They were botanical gardens in the sense of building up collections of plants and exchanging seeds with other gardens around the world, although their collection policies were determined by those in day-to-day charge of them. They tended to become little more than beautifully maintained parks and were, indeed, often under general parks administrations.
Community engagement The second half of the 20th century saw increasingly sophisticated educational, visitor service, and interpretation services. Botanical gardens started to cater for many interests and their displays reflected this, often including botanical exhibits on themes of
evolution,
ecology or
taxonomy, horticultural displays of attractive
flowerbeds and
herbaceous borders, plants from different parts of the world, special collections of plant groups such as
bamboos or
roses, and specialist glasshouse collections such as tropical plants,
alpine plants,
cacti and
orchids, as well as the traditional herb gardens and medicinal plants. Specialised gardens like the
Palmengarten in
Frankfurt, Germany (1869), one of the world's leading orchid and
succulent plant collections, have been very popular.
Plant conservation Plant conservation and the heritage value of exceptional historic landscapes were treated with a growing sense of urgency through the 20th century. Specialist gardens were sometimes given a separate or adjoining site to display native and indigenous plants.
21st century New gardens , established in 2000 in
Cornwall, England, includes a modern botanical garden exploring the theme of
sustainability. Botanical gardens have continued to be built in the 21st century, such as the first botanical garden in
Oman, which is planned to be one of the largest gardens in the world, with the first large-scale
cloud forest in a huge glasshouse. Development of botanical gardens in China over recent years has been remarkable, including the
Hainan Botanical Garden of Tropical Economic Plants at Guangzhou,
South China Botanical Garden, the
Xishuangbanna Botanical Garden of Tropical Plants, and the
Xiamen Botanic Garden. In
developed countries, on the other hand, many have closed for lack of financial support, especially those attached to universities.
Missions and strategy The
Center for Plant Conservation at
St Louis, Missouri, coordinates the conservation of native North American species. The 2006
North American Botanic Garden Strategy for Plant Conservation sets out its goals to document and conserve plant diversity, to use that diversity sustainably, to educate the public about plant diversity, build conservation capacity, and to build support for the strategy itself. A 2024 review in a special issue of the
Journal of Zoological and Botanical Gardens on the sustainability of botanic gardens noted their increasing roles in conservation and research, and the many new gardens created since 1950. In its view, the gardens are being "reinvent[ed]" to serve the goals of conservation, sustainability, and social engagement. It observes that historically, the gardens emerged in an era that saw both the growth of modern science and the colonial era. In response, the gardens have engaged in decolonising and in "new socio-environmental missions". Finally, it attempts to view the gardens on a global scale. A 2023 historical review by Chinese botanists similarly notes the long history of botanical gardens from the medicinal gardens of the first universities in
Renaissance Europe, and from China's ancient
Shennong herbal garden tradition. The gardens have in its view continuously adapted to new demands in a changing environment, coming to serve the "core mission of
ex situ conservation". Botanical gardens must find a compromise between the need for peace and seclusion, while at the same time satisfying the public need for information and visitor services that include restaurants, information centres and sales areas that bring with them rubbish, noise, and crowding. Attractive
landscaping and planting design sometimes compete with scientific interests—with science now often taking second place. Some gardens are now heritage landscapes that are subject to constant demand for new exhibits and exemplary environmental management. == See also ==
