he immediately traveled to Washington and gave the plants to the superintendent and botanist of the United States Botanic Garden W. D. Breckenridge. 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: The Garden Court Rare and Endangered Plants (rare species, endangered species) Plant Exploration Orchid House (orchids) Medicinal Plants (medicinal plants) Desert (desert species) Hawaii Garden Primeval (primeval) Plant Adaptation Jungle (jungle species; this is the largest of the rooms, and includes a second-story catwalk so that the jungle canopy may be observed from both below and above) Children's Garden (courtyard; features many thriving temperate annuals used to encourage interest in plants) Southern Exposure (courtyard), on the south side of the building, is surrounded by glass walls, receiving more warmth. It features many plants from the Southeast and Southwest, which would not be able to live in the colder District of Columbia climate if not for the microclimate) Except for the Hawaiian house, the galleries, and the south lobby, none of the conservatory has air conditioning. Each room is closely monitored by 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
