The Columbian Institute for the Promotion of Arts and Sciences in Washington, DC first suggested the creation of the Botanic Garden in 1816. In 1820 it was given land by an act of Congress. The land was located west of the Capitol extending from First Street to Third Street between Pennsylvania and Maryland Avenues. The facility ceased to operate in 1837 when the society stopped holding meetings. However it was re-instituted in 1842 when the Wilkes expedition of the South Seas brought back a collection of plants. In 1838, Charles Wilkes set out on the United States Exploring Expedition commissioned by Congress to circumnavigate the globe and explore the Pacific Ocean. During this trip, Wilkes collected live and dried specimens of plants and was one of the first to use wardian cases to maintain live plants on long voyages. Wilkes returned in 1842 with a massive collection of plants previously unknown in the United States. The dried specimens comprised the core of what is now the National Herbarium, an herbarium curated by the Smithsonian Institution'sNational Museum of Natural History. The live specimens and seeds came to be housed in the Old Patent Office greenhouse, and were cared for there until 1850. At that time, a botanic garden was built to house the collection in front of the Capitol, where the Capitol reflecting pool is now located. In 1933, the building was moved to its present location, just to the southwest of the Capitol, bordered by Maryland Avenue on the north, First Street on the east, Independence Avenue on the south, and Third Street on the west. The building was closed for renovations on September 1, 1997, and reopened to the public on December 11, 2001. At the time of closure for renovation, plants in the collection were either placed in storage at the USBG Production Facility, retired to greenhouses in Florida, or composted.
Facilities
The USBG proper consists of three locations: the Conservatory, Bartholdi Park, and the Production Facility. The Conservatory is a conservatory housed in a Lord & Burnham greenhouse. It is divided into separate rooms, each simulating a different habitat:
Except 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 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'. Bartholdi Park lies just south of the Conservatory, across Independence Avenue. It is named for the Bartholdi Fountain in the garden's center designed by Frédéric Bartholdi. One of the goals of this garden is to provide inspiration and ideas for home gardeners who visit it. It displays a variety of small structured and non-structured gardens, and infuses color, shape, and planting themes. One section of the garden is certified as a National Wildlife FederationBackyard Wildlife Habitat. The Park also houses the administrative building for the United States Botanic Garden. The Production Facility in southwest D.C. is used for growing and storing plants for propagation, for collection maintenance, or for display in upcoming annual shows. The USBG participates in CITES, which means that it cares for plants seized by Customs. It specializes in orchids and succulents.
Wilkes Plants
There are four plants in the garden that are believed to be directly related to the original Wilkes Expedition.
The Vessel Fern situated in the Jungle, is a fern believed to be the direct progeny of the Vessel Fern brought back on Wilkes' ship. Because of the lifespan of Vessel Ferns, it is highly unlikely that the present fern is the original; however it is believed that the present fern is a direct descendant and genetically identical to the original.
The Ferocious Blue Cycad is a cycad questionably one of the original Wilkes plants. Due to its size and possible age, some believe this plant to have come back with the expedition in 1842; unfortunately, early records are incomplete and inaccurate, so this is left to speculation.
The Queen Sagos Cycas circinalis, which are cycads, live in the Garden Court. The Botanic Garden cares for both a male and a female of the species, and both were brought back with the Wilkes Expedition.
