The Arboretum began during the years 1904 to 1912. It all started thru the efforts of Helen Byrne. She was the wife of, James Byrne a lawyer from the New York city. Jameswas able to purchase six properties which were all collectively referred as the Upper Fields Planting Farm. The Byrnes then hired an architect who was an expert in landscape, James Greenleaf. Between the years 1904 to 1910, he created perennial borders, hedges andfruit tees. Some of the more memorable features from this period were the Arbor Rose, the Pool Circular, the Green Court Garden. 

Then, in the year 1913, William Coe bought the house and the whole three hundred fifty three acre estate. Since then, they began the landscaping and planting of the estate under the tutelage of the landscaping firm of Boston, specifically AR Sargent and Guy Lowell. In the year 1915, Sargent and Lowell saw the transport of Fairhaven Copper Beach tree which came from Fairhaven Massachusetts. The two huge trees with ball roots thirty feet in diameter were slowly ferried across and through Long Island in the middle of winter. Roads were widened and wires were removed albeit temporarily in order to make way for the trees. Though only a single tree was able to survive from the original two that were ferried it is still standing today.

The Coes preference to rare tree species as well as collection of plants made the whole estate a marvel of botanical prowess.
