The Sarah P. Duke Gardens are on the grounds of Duke University in Durham, NC. It was the brainchild of Dr. Frederic M. Hanes, an original faculty member of Duke Medical School. A botanical enthusiast, Dr. Hanes passed a debris-filled ravine on the way to the school every day, and so persuaded Ms. Duke, who was the widow of one of the university's founders, to finance a public garden on the land. The gardens were built, but unfortunately heavy summer rains and floods ruined them. Sarah Duke had passed away, but Dr. Hanes was still around, so he convinced Sarah's daughter, Mary Duke Biddle, to bankroll a new garden on higher ground and name it in honor of her mother. The Sarah P. Duke Gardens were dedicated in April 1939. It was designed by Ellen Biddle Shipman, an early pioneer in American landscape design. It's one of the remaining examples of her work. It has since expanded to 5 miles of trails and walkways across 55 acres.
