The Arboretum will also honor those they call the Founders with a special event Sunday, May 22 from 2 until 4 p.m. Each year, The Arboretum hosts the Founders Lecture series. The organization recently held a Founders Valentine Tea and there will be a Founders Day event in May. So, who and what are Founders? A document on file at The Visitor Center proclaims, “those individuals, clubs, organizations, or businesses who made a generous donation to the Friends of The Arboretum from 1992 to December 31, 1994 are to be named Founders.” Many of the Founders have served as leaders of The Arboretum, Friends Board and Advisory Board members, Bur Oak Society honorees, and energetic volunteers. Over 25 years, the organization has lost some Founders, but they are a sturdy crew, with close to 60 individual and organization members now, and many of them attended the Founders Valentine Tea. Founder Virginia Long, who became the first President of the Friends in 1992, recalls approaching Dr. Dewayne Ingram, then chair of the Department of Horticulture at the University of Kentucky, in search of a way to raise funds to support the recently opened Arboretum. The result was the establishment of a generous group of Friends, like Ruth and Bob Straus, with their spirit of giving and volunteering to support The Arboretum.
