The botanical gardens in New York are a National Landmark; they were established in 1891 and are located in the Bronx. The gardens cover 250 acres within Bronx Park. Visitors can see flowers and plants in bloom throughout the year. Within the site there are 50 individual gardens and plant collections including 50 acres of original New York forest. The botanical garden's New York forest is split in two by the Bronx River which is the only fresh water river in the city. A stone mill dating back to 1840 sits on the bank of the river.
The botanical garden has a greenhouse from the 1890s; a rose garden which was planted in 1916; a 37 acre rock garden and a herbarium. The garden has several works of art and sculptures, fountains and other water features. Among the various flower gardens the Azalea Garden; Confer Arboretum and a Native Plant Garden with plants from northeastern North America are in bloom all year round. The gardens are continually being maintained and nurtured.
