The Ontario Horticultural Association is Keeping Ontario Beautiful.

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 pursues its mission by:

  • Providing grants for trees and community beautification projects throughout Ontario.
  • Developing programs in the areas of Conservation and the Environment, youth and horticulture.
  • Providing support to its member horticultural societies in the form of shared insurance plans, promotion, speaker lists, procedure manuals, volunteer recognition, projects, events and web sites.
  • Holding an annual convention and providing educational opportunities for members.
  • Publishing items of a horticultural or environmental nature such as the Trillium newsletter, the Rain Barrel Booklet and the Ontario Judging Standards.

The Ontario Horticultural Association depends on the support of its members and charitable donations to carry out its work. You are encouraged to support the OHA as a volunteer with a horticultural society or with a charitable donation.

Societies Are Keeping Ontario Beautiful.

There are 282 Horticultural Societies in Ontario working on projects to Keep Ontario Beautiful. The projects include a wide variety of activities like beautifying local parks, planting boxes in downtown areas, and creating and maintaining public gardens around government buildings, hospitals, health and hospice centres. Examples of these projects can be found here.

Our Vision.

The OHA will create a supportive environment for gardeners of all ages. We will foster the growth of our member societies and encourage the use of eco-friendly horticultural practices to promote the production of food, the beautification of our communities and the conservation of our environment.
