Welcome to the National Tropical Botanical Garden The importance of plants to life on earth is immeasurable. We depend upon them for the air we breathe, for the food we eat, for shelter, and for medicine. Ninety percent of all plant and animal species on our planet exist in the tropics — that warm moist belt that circles the earth. And it is in these regions where the extinction rate is the highest. Species are disappearing faster than anyone knows. They cannot be replaced. The National Tropical Botanical Garden is dedicated to preserving tropical plant diversity and stemming this tide of extinction – through plant exploration, propagation, habitat restoration, scientific research, and education. NTBG’s gardens and preserves are safe havens for at-risk species that otherwise might disappear forever. National Tropical Botanical Garden – Saving Plants, Saving People Watch VideosExcept for the Hawaiian house, the galleries, and south lobby, none of the conservatory has air conditioning. Each room is closely monitored by a computer-operated sensors to maintain the environment best suited to the plants in that room. Humidity, sunlight and temperature are regulated by means of a misting system, retractable shades and levered windows. All plants are watered daily by hand. Construction was completed on the 3-acre (12,000 m2) National Garden on the Botanic Garden’s west border, in October 2006 and the garden includes a regional garden of plants native to the Atlantic Coastal Plain and Piedmont, a rose garden, a butterfly garden, and the First Ladies Water Garden, a water garden in memory of the First Ladies of the United States.The National Garden construction was funded by the National Fund for the U.S. Botanic Garden which now exists as a ‘friends group’.Visit Our Tropical Gardens NTBG has five gardens in four locations.

One section of the garden is certified as a National Wildlife Federation Backyard Wildlife Habitat. The Park also houses the administrative building for the United States Botanic Garden.The Columbian Institute for the Promotion of Arts and Sciences in Washington, D.C., first suggested the creation of the Botanic Garden in 1816. The idea of establishing a botanic garden in Washington, D.C., was also supported by the Washington Botanical Society, organized in 1817, many of whose members were also members of the Columbian Institute, however this society disbanded in 1826.In 1820, President James Monroe set aside 5 acres (20,000 m2) for a “national greenhouse.” Dr. Edward Cutbush, founder and first president of the Columbian Institute, was one of the earliest advocates for a plant repository and saw the necessity for a botanical garden “where various seeds and plants could be cultivated, and, as they multiplied, distributed to other parts of the Union.”The National Tropical Botanical Garden is dedicated to preserving tropical plant diversity and stemming this tide of extinction – through plant exploration, propagation, habitat restoration, scientific research, and education. NTBG’s gardens and preserves are safe havens for at-risk species that otherwise might disappear forever.National Tropical Botanical Garden and its gardens are located in the only tropical climate zones in the United States. While other major gardens can grow tropical plants in greenhousesIn 1838, Lt. Charles Wilkes set out on the United States Exploring Expedition commissioned by Congress to circumnavigate the globe and explore the Pacific Ocean. Between the years 1838–1842, the expedition, consisting of six government ships, traveled 87,000 miles and collected a large assortment of horticultural and botanical specimens. These formed the nucleus of the present garden. The expedition also confirmed that Antarctica was a continent.The garden “was formally placed under the jurisdiction of the Joint Committee on the Library of Congress in 1856 and has been administered through the Office of the Architect of the Capitol since 1934. The Architect of the Capitol has served as Acting Director of the United States Botanic Garden and is responsible for the maintenance and operation of the Garden and for any construction, changes, or improvements made.”It was felt that the botanic garden must be removed because when Congress established the location of the Grant Memorial in the garden-area, technically, it forced the garden out. “Such was the intention of Congress.”A plant production facility in Anacostia, Washington, D.C., includes greenhouse bays and a support facility for the garden. The U.S. Botanic Garden Production Facility, covers 85,000 square feet (7,900 m2) under glass, and is the largest support facility for a botanic garden in the United States. It houses collections currently not on display, including plants recuperating. Seasonal plants are also grown at the facility for use in the Supreme Court, Library of Congress and for replenishing the Capitol grounds. An estimated 100,000 mums, pansies, cabbage, kale and other annuals and perennials per year are grown in the facility. Additionally, foliage plants for the Senate offices and palm trees for Capitol Hill events as well as special seasonal displays such as Easter lilies and poinsettias are all grown on site. “According to staff botanists, there are about 50,000 plants on hand at the production facility at any one time.The Commission of Fine Art made recommendation that the Mount Hamilton tract be acquired for a national botanic garden and arboretum; by purchasing 400 acres (1.6 km2) of land, at least 800 acres (3.2 km2) of Government-owned lands will be made available. Also, a park entrance to the city from the north will be provided. Additionally, the public features of the “present” Botanic Garden be transferred from the west side of the Capitol to the north side to lands already owned by the Government.
