Tower Hill Botanic Garden opened in 1986 but its history as the Worcester County Horticultural Society dates back to the 1840s, and the Library goes back almost as far. Early library holdings began with donations from founders and members. Today the Library provides access to institutional and garden history records as well as the rare book collection to researchers. The Library regularly exhibits materials from our Special Collections.
