NEW YORK — Property from the estate of noted horticulturist, philanthropist and heir to the Listerine fortune Rachel “Bunny” Mellon is going on the auction block this fall.

Over 2,000 paintings, jewelry, furniture and decorative objects are estimated to bring more than $100 million, according to Sotheby’s.

The proceeds will benefit The Gerard B. Lambert Foundation, which supports The Oak Spring Garden Library in Upperville, Virginia.

The library houses Mellon’s collection of rare books, manuscripts and works of art related to landscape design, horticulture and natural history that is visited by scholars worldwide.

Mellon was the widow of philanthropist Paul Mellon. She died in March at 103.
