Past Presidents’ Council
Prior to the 2019 convention, during the afternoon of June 29, a tree dedication ceremony took place at the Past Presidents’ Oak Grove at the Guelph Arboretum. Two Bur Oaks (Quercus macrocarpa) that had been planted earlier were dedicated to mark the passing of John Smith (President 1969/70) and Kathleen Petrie (President 2000).
The Past Presidents’ Council was created in 1964.
What is their role in the OHA?
- The Council acts in an advisory capacity to the Board on Association-related issues. The immediate Past President serves as the Council’s representative on the OHA Executive.
- The Chair of the Past Presidents’ Council and the immediate Past President both sit on the OHA Awards Committee. The Council currently sponsors the Frances Lemke Youth Activity Award.
- Members of the Council take on occasional projects from time to time and work on various OHA committees.
- They serve as facilitators in disputes when called upon.
The Guelph Arboretum
The Arboretum at the University of Guelph is somewhat modeled after the Arnold Arboretum of Harvard University which is 100 years older. Plantings started in 1971 and are now maturing to produce a beautiful landscape, within which The Arboretum continues to develop specialized gardens, botanical collections, and gene conservation programs. Labels are maintained at the base of all woody plants in the collections that are listed on The Arboretum map.
The Ontario Horticultural Association Oak Grove was established as part of the Arboretum in Guelph in 1978. The First tree planted was a Scarlet Oak honouring Mabel Stewart. In 1981 two trees were planted to honour Harry Occomore and Ellen Bigelow. The Association acquired a plot of land to extend the existing area and oak trees were planted and benches dedicated to the memory of former presidents.
The Ontario Horticultural Association is a volunteer, charitable organization whose mission is to provide leadership and assist in the promotion of education and interest in all areas of horticulture and related environmental issues in Ontario, through an expanding network of horticultural societies dedicated to the beautification of their communities.
The Ontario Horticultural Association appreciates the support we receive from organizations that share similar values to our own and we thank them for helping to promote the many programs we deliver across Ontario.
