William Prince (1725-1802) was a horticulturist and the second proprietor of the Prince Nursery in Flushing, Long Island. It was established by his father Robert, and grew to be the first large commercial nursery in America. It continued throughout the British occupancy during the American Revolution under heavy guard by British troops. After the war, the original land was taken over by Prince's son Benjamin and named the Old American Nursery. Prince's other son, also named William, established the Linnean Botanic Garden and Nursery.
