Bonsai Museum - Brooklyn Botanic Garden

Brooklyn Botanic Garden's extensive bonsai collection is one of the finest in the world. The collection of approximately 350 trees is the second oldest in the country and one of the largest on public display outside Japan, with as many as 30 specimens on exhibit at any given time. Cold-temperate trees form the core of the collection, but tropical, subtropical, Mediterranean, and warm-temperate species are also represented.
