All told, it contains 25 of about 100 Oahu trees designated as exceptional. The garden also contains several memorials and sculptures: Botanical gardens A botanical garden or botanic garden is a garden with
261-491: 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,
348-403: A department of an educational institution, it may be related to a teaching program. In any case, it exists for scientific ends and is not to be restricted or diverted by other demands. It is not merely a landscaped or ornamental garden, although it may be artistic, nor is it an experiment station or yet a park with labels on the plants. The essential element is the intention of the enterprise, which
435-596: A documented collection of living plants for the purpose of scientific research, conservation, display, and education. It is their mandate as a botanical garden that plants are 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 glasshouses or shadehouses , again with special collections such as tropical plants , alpine plants , or other exotic plants that are not native to that region. Most are at least partly open to
522-528: A factor that probably contributed to the creation of botany as an independent discipline rather than a descriptive adjunct to medicine. 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 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
783-551: A protective response. The first such plant receptors were identified in rice and in Arabidopsis thaliana . Plants have some of the largest genomes of all organisms. The largest plant genome (in terms of gene number) is that of wheat ( Triticum aestivum ), predicted to encode ≈94,000 genes and thus almost 5 times as many as the human genome . The first plant genome sequenced was that of Arabidopsis thaliana which encodes about 25,500 genes. In terms of sheer DNA sequence,

#17327722960421044-457: 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. With the increase in maritime trade , ever more plants were being brought back to Europe as trophies from distant lands, and these were triumphantly displayed in
1131-470: A year. Historically, botanical gardens exchanged plants through the publication of seed lists (these were called Latin : Indices Seminae in the 18th century). This was a means of transferring both plants and information between botanical gardens. This system continues today, although the possibility of genetic piracy and the transmission of invasive species has received greater attention in recent times. The International Association of Botanic Gardens
1218-404: Is diploid (with 2 sets of chromosomes ), gives rise to the next generation, the gametophyte , which is haploid (with one set of chromosomes). Some plants also reproduce asexually via spores . In some non-flowering plants such as mosses, the sexual gametophyte forms most of the visible plant. In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and
1305-547: Is a similar process. Structures such as runners enable plants to grow to cover an area, forming a clone . Many plants grow food storage structures such as tubers or bulbs which may each develop into a new plant. Some non-flowering plants, such as many liverworts, mosses and some clubmosses, along with a few flowering plants, grow small clumps of cells called gemmae which can detach and grow. Plants use pattern-recognition receptors to recognize pathogens such as bacteria that cause plant diseases. This recognition triggers
1392-488: 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. Later, in the 18th century, they became more educational in function, demonstrating

The botanical garden of Quito is a park, a botanical garden, an arboretum and greenhouses of 18,600 square meters that is planned to increase, maintain the plants of
1566-496: Is known as botany , a branch of biology . All living things were traditionally placed into one of two groups, plants and animals . This classification dates from Aristotle (384–322 BC), who distinguished different levels of beings in his biology , based on whether living things had a "sensitive soul" or like plants only a "vegetative soul". Theophrastus , Aristotle's student, continued his work in plant taxonomy and classification. Much later, Linnaeus (1707–1778) created
1653-669: 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. The large number of plants needing description were often listed in garden catalogues; and at this time Carl Linnaeus established
1740-1101: Is the acquisition and dissemination of botanical knowledge. A contemporary botanic garden is a strictly protected green area, where a managing organization creates landscaped gardens and holds documented collections of living plants and/or preserved plant accessions containing functional units of heredity of actual or potential value for purposes such as scientific research, education, public display, conservation, sustainable use, tourism and recreational activities, production of marketable plant-based products and services for improvement of human well-being. Worldwide, there are now about 1800 botanical gardens and arboreta in about 150 countries (mostly in temperate regions) of which about 550 are in Europe (150 of which are in Russia ), 200 in North America , and an increasing number in East Asia. These gardens attract about 300 million visitors
1827-526: Is the oldest botanical garden in Hawaii, and listed on the National Register of Historic Places . In 1853, Queen Kalama leased 4.6 acres (1.9 ha) of land to William Hillebrand , a German physician and botanist who built his home and planted trees on the site. During his stay, he introduced a number of plants to Hawaii, as well as deer and mynah birds. Many of the large trees growing today on

The staff will normally include botanists as well as gardeners. Many botanical gardens offer diploma/certificate programs in horticulture, botany and taxonomy. There are many internship opportunities offered to aspiring horticulturists. As well as opportunities for students/researchers to use
2001-670: 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 hortus medicus of Leyden in 1601

The Koishikawa Botanical Garden in Tokyo, with its origin going back to the Tokugawa shogunate 's ownership, became in 1877 part of the Tokyo Imperial University . In Sri Lanka major botanical gardens include the Royal Botanic Gardens, Peradeniya (formally established in 1843), Hakgala Botanical Gardens (1861) and Henarathgoda Botanical Garden (1876). Jardín Botánico de Quito
2349-1001: 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. The Auburn Botanical Gardens , 1977, located in Sydney's western suburbs , are one of the popular and diverse botanical gardens in the Greater Western Sydney area. Major botanical gardens in New Zealand include Dunedin Botanic Gardens , 1863; Christchurch Botanic Gardens , 1863; Ōtari-Wilton's Bush , 1926; and Wellington Botanic Gardens , 1868. Hong Kong Botanic Gardens , 1871 (renamed Hong Kong Zoological and Botanical Gardens in 1975), up from

Plants reproduce asexually by growing any of a wide variety of structures capable of growing into new plants. At the simplest, plants such as mosses or liverworts may be broken into pieces, each of which may regrow into whole plants. The propagation of flowering plants by cuttings
2523-751: The glaucophytes , in the clade Archaeplastida . There are about 380,000 known species of plants, of which the majority, some 260,000, produce seeds . They range in size from single cells to the tallest trees . Green plants provide a substantial proportion of the world's molecular oxygen; the sugars they create supply the energy for most of Earth's ecosystems and other organisms , including animals, either eat plants directly or rely on organisms which do so. Grain , fruit , and vegetables are basic human foods and have been domesticated for millennia. People use plants for many purposes , such as building materials , ornaments, writing materials , and, in great variety, for medicines . The scientific study of plants
2610-506: The "Father of Botany". There is some debate among science historians whether this garden was ordered and scientific enough to be considered "botanical", and suggest it more appropriate to attribute the earliest known botanical garden in Europe to the botanist and pharmacologist Antonius Castor , mentioned by Pliny the Elder in the 1st century. Though these ancient gardens shared some of

Certainly the founding of many early botanic gardens was instigated by members of the medical profession. In the 17th century, botanical gardens began their contribution to a deeper scientific curiosity about plants. If

Plant cells differentiate into multiple cell types, forming tissues such as the vascular tissue with specialized xylem and phloem of leaf veins and stems , and organs with different physiological functions such as roots to absorb water and minerals, stems for support and to transport water and synthesized molecules, leaves for photosynthesis, and flowers for reproduction. Plants photosynthesize , manufacturing food molecules ( sugars ) using energy obtained from light . Plant cells contain chlorophylls inside their chloroplasts, which are green pigments that are used to capture light energy. The end-to-end chemical equation for photosynthesis is: This causes plants to release oxygen into

These contained a hortus , a garden used mostly for vegetables, and another section set aside for specially labelled medicinal plants and this
4089-442: The classification systems being developed by botanists in the gardens' museums and herbaria. Botanical gardens had now become scientific collections, as botanists published their descriptions of the new exotic plants, and these were also recorded for posterity in detail by superb botanical illustrations. In this century, botanical gardens effectively dropped their medicinal function in favour of scientific and aesthetic priorities, and

With the rapid expansion of European colonies around the globe in the late 18th century, botanic gardens were established in the tropics, and economic botany became a focus with the hub at the Royal Botanic Gardens, Kew , near London. Over the years, botanical gardens, as cultural and scientific organisations, have responded to
4959-583: The great majority, some 283,000, produce seeds . The table below shows some species count estimates of different green plant (Viridiplantae) divisions . About 85–90% of all plants are flowering plants. Several projects are currently attempting to collect records on all plant species in online databases, e.g. the World Flora Online . Plants range in scale from single-celled organisms such as desmids (from 10 micrometres (μm) across) and picozoa (less than 3 μm across), to

Then, in the 19th and 20th centuries, the trend was towards a combination of specialist and eclectic collections demonstrating many aspects of both horticulture and botany. The idea of "scientific" gardens used specifically for the study of plants dates back to antiquity. 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

Biotic factors that affect plant growth include crowding, grazing, beneficial symbiotic bacteria and fungi, and attacks by insects or plant diseases . Frost and dehydration can damage or kill plants. Some plants have antifreeze proteins , heat-shock proteins and sugars in their cytoplasm that enable them to tolerate these stresses . Plants are continuously exposed to
5829-724: The physicians (referred to 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. All of these botanical gardens still exist, mostly in their original locations. The tradition of these Italian gardens passed into Spain Botanical Garden of Valencia , 1567) and Northern Europe , where similar gardens were established in

In principle, their role
6264-824: The purposes of scientific research, conservation, display and education." The following definition was produced by staff of the Liberty Hyde Bailey Hortorium of Cornell University in 1976. It covers in some detail the many functions and activities generally associated with botanical gardens: A botanical garden is a controlled and staffed institution for the maintenance of a living collection of plants under scientific management for purposes of education and research, together with such libraries, herbaria, laboratories, and museums as are essential to its particular undertakings. Each botanical garden naturally develops its own special fields of interests depending on its personnel, location, extent, available funds, and
6351-544: The rubber plant was introduced to Singapore. 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 ( Hevea brasiliensis ) was introduced from Kew, which had itself imported the plant from South America . Other examples include cotton from
6438-743: 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 gardens in Tenochtitlan established by king Nezahualcoyotl , also gardens in Chalco (altépetl) and elsewhere, greatly impressed
6525-428: The sites used for the UK's dispersed National Plant Collection , usually holding large collections of a particular taxonomic group, would call themselves "botanic gardens". This has been further reduced by Botanic Gardens Conservation International to the following definition which "encompasses the spirit of a true botanic garden": "A botanic garden is an institution holding documented collections of living plants for
6612-469: The smallest published genome is that of the carnivorous bladderwort ( Utricularia gibba) at 82 Mb (although it still encodes 28,500 genes) while the largest, from the Norway spruce ( Picea abies ), extends over 19.6 Gb (encoding about 28,300 genes). Plants are distributed almost worldwide. While they inhabit several biomes which can be divided into a multitude of ecoregions , only the hardy plants of
6699-404: The system of binomial nomenclature which greatly facilitated the listing process. Names of plants were authenticated by dried plant specimens mounted on card (a hortus siccus or garden of dried plants) that were stored in buildings called herbaria , these taxonomic research institutions being frequently associated with the botanical gardens, many of which by then had "order beds" to display
6786-417: The term "botanic garden" came to be more closely associated with the herbarium, library (and later laboratories) housed there than with the living collections – on which little research was undertaken. 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
6873-401: The terms of its charter. It may include greenhouses, test grounds, an herbarium, an arboretum, and other departments. It maintains a scientific as well as a plant-growing staff, and publication is one of its major modes of expression. This broad outline is then expanded: The botanic garden may be an independent institution, a governmental operation, or affiliated to a college or university. If
6960-847: 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
7047-519: The various kinds of organizations known as botanical gardens, there are many that are in modern times public gardens with little scientific activity, and it cited a tighter definition published by the World Wildlife Fund and IUCN when launching the "Botanic Gardens Conservation Strategy" in 1989: "A botanic garden is a garden containing scientifically ordered and maintained collections of plants, usually documented and labelled, and open to
7134-439: 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 hortus academicus . His Exoticorum libri decem (1605) is an important survey of exotic plants and animals that is still consulted today. The inclusion of new plant introductions in botanic gardens meant their scientific role
7221-558: Was called the herbularis or hortus medicus —more generally known as a physic garden, and a viridarium or orchard. These gardens were probably given impetus when Charlemagne issued a capitulary , the Capitulary de Villis, which listed 73 herbs to be used in the physic gardens of his dominions. Many of these were found in British gardens even though they only occurred naturally in continental Europe, demonstrating earlier plant introduction. Pope Nicholas V set aside part of
7308-556: Was formed in 1954 as a worldwide organisation affiliated to the International Union of Biological Sciences . More recently, coordination has also been provided by Botanic Gardens Conservation International (BGCI), which has the mission "To mobilise botanic gardens and engage partners in securing plant diversity for the well-being of people and the planet". BGCI has over 700 members – mostly botanic gardens – in 118 countries, and strongly supports
7395-643: Was marked by introductions from the Cape of South Africa – including ericas , geraniums , pelargoniums , succulents, and proteaceous plants – while the Dutch trade with the Dutch East Indies resulted in a golden era for the Leiden and Amsterdam botanical gardens and a boom in the construction of conservatories. The Royal Gardens at Kew were founded in 1759, initially as part of
7482-658: Was now widening, as botany gradually asserted its independence from medicine. 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
7569-442: 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). During these times,
