Untermyer Gardens. Yonkers, New York.
"In 1899 Samuel Untermyer purchased Greystone, the former estate of Samuel Tilden. In the forty one years Untermyer owned Greystone, he transformed the gardens and greenhouses into some of the most celebrated gardens in America. After expanding the estate through property purchases to the north and east of the original estate, he hired Beaux Arts architect Welles Bosworth to design gardens around 1916. These gardens sprawled over 150 acres overlooking the Hudson River and were maintained by 60 gardeners and supplied by 60 greenhouses." Source: Official Garden Website.
