New York Metropolitan Flora Project
In 1990, the Garden embarked on the New York Metropolitan Flora project (NYMF), a multiyear effort to document the flora in all counties within a 50-mile radius of New York City. The findings, as documented in the metropolitan plant encyclopedia, consists of a series of comprehensive pages on the plants of the New York metropolitan region.
The herbarium includes 300,000 specimens of preserved plants. The collection is worldwide in scope, with concentration on plants of the greater New York area and cultivated plants.
The Garden's library, including the Science Library and the Rare Book Room, provides reference services to home gardeners, staff, and the professional horticultural community.
