Planting Fields Arboretum

Why it's listed
Planting Fields Arboretum occupies 409 acres near Oyster Bay on Long Island, once the country estate of William Robertson Coe. Land first cultivated by the Matinecock Indians later became Quaker farms and then asparagus fields. In 1904 the James Byrne family bought farmland here, and Coe acquired the estate in 1913. Guy Lowell enlarged the greenhouses and remodeled the garden house in 1915. After the Byrne residence burned in 1918, Walker and Gillette designed Coe Hall, a Jacobethan Revival house of cut stone and half timbering finished in 1920, with interiors overseen by Charles of London. The firm also designed the stables, garage, gate house and laundry. Fred Dawson of the Olmsted Brothers laid out the heather garden and main road. Coe also brought the eighteenth-century Carshalton Gates from England. He deeded the property to New York State in 1949 for educational use, and it now operates as a public horticultural center.
Significance in brief: The nomination argues the estate shows the rapid shift of Long Island's northwest shore from farmland to elegant country seats. It is also significant for its Jacobethan Revival main house and well-designed outbuildings by noted architects. Its lavishly planted grounds evolved under Coe's close supervision into a horticultural showplace.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
