Hildene, the former summer home of Robert Todd Lincoln and his wife Mary Harlan Lincoln, located in Manchester Center, Vermont.
Robert was one of four - and the only surviving child of Abraham and Mary Todd Lincoln.
According to Wiki, "The garden [At Hildene] is especially noted for its collection of over 1,000 herbaceous peonies.”
I took this photo on a visit to Hildene several years ago.
This is the back of the house.
