The U.S. Botanic Garden—located adjacent to the Capitol in a triangle between Maryland Ave SW, Washington Ave SW, and First Street—is rooted in the earliest planning of the capital city. Many of the Founding Fathers believed that a living repository for plants would have countless benefits, from the production of food and medicine to the scientific study of international specimens to the enjoyment of aesthetic beauty. George Washington himself wrote an impassioned letter in 1796 about how a botanic garden should be included in the city plan, even suggesting a few feasible locations.
