Brooklyn Botanic Garden is located at 900 Washington Avenue, Brooklyn, NY 11225. A century ago, Brooklyn Botanic Garden’s founders had the vision to transform a city ash heap into a premier botanic garden in the heart of the borough. Since the Garden first opened its gates to the public, it has been a vibrant place for education, research, world-class horticulture, and sanctuary. Join us this summer in celebrating our first 100 years and our exciting plans for the future!
