Mary Wharton

Beginning in the late 1950s, Wharton bought parcels of land on the Kentucky River and founded the Floracliff Nature Sanctuary in 1989; it was dedicated as a Kentucky State Nature Preserve on March 15, 1996. Wharton protected part of the sanctuary using a scenic easement. In fact, she was the first to use a scenic easement in Kentucky. Wharton also cofounded the Land and Nature Trust of Bluegrass to help preserve many parts of the bluegrass region such as Raven Run, greenway parks, and the Paris-Lexington corridor. She held the positions of chairman or President of the Board for this organization several times. She was also a member of The Kentucky Nature Conservatory Board and the Kentucky River Steering Committee.

Wharton died on November 28, 1991, in Lexington, Kentucky.

Besides being an avid plant collector, Wharton was also a writer. Wharton collaborated with Roger Barbour on two field guides, Wildflowers and Ferns of Kentucky (1971) and Shrubs of Kentucky (1973), and a natural history of the Inner Blueglass Region, Bluegrass Land and Life. In addition, Wharton edited diaries and letters of Martha McDowell Buford Jones, a Confederate wife, published in 1986 as Horse World of the Bluegrass and Peach Leather and Rebel Grey.

Mary Eugenia Wharton (October 12, 1912 – November 28, 1991) was an American botanist, author, and environmental activist.

Wharton was born in Jessamine County, Kentucky on October 12, 1912, the younger of two daughters of Joseph Felix and Mayme (née Davis) Wharton. In 1916, the family moved to Lexington. Wharton graduated from the University of Kentucky in 1935 with a bachelor's degree in botany and geology. She then received both a master's degree in 1936 and a doctorate from the University of Michigan in 1946. In 1942, she collected dewberry, a berry closely related to blackberries, from Montgomery County, Kentucky. This berry proved to be a new species and was named Rubus whartoniae in her honor.
