The New York Botanical Garden is a botanical garden located at Bronx Park in the Bronx, New York City. Established in 1891, it is located on a 250-acre site that contains a landscape with over one million living plants; the Enid A. Haupt Conservatory, a greenhouse containing several habitats; and the LuEsther T. Mertz Library, which contains one of the world's largest collections of botany-related texts. As of 2016, over a million people visit the New York Botanical Garden annually.
NYBG is also a major educational institution, teaching visitors about plant science, ecology, and healthful eating through NYBG's interactive programming. Nearly 90,000 of the annual visitors are children from underserved neighboring communities. An additional 3,000 are teachers from New York City's public school system participating in professional development programs that train them to teach science courses at all grade levels.
NYBG operates one of the world's largest plant research and conservation programs. Since 1967, the garden has been listed as a National Historic Landmark, and several buildings have been designated as official New York City landmarks.
