Who We Are

The Ontario Horticultural Association (OHA) is a volunteer charitable organization that encourages interest in gardening and related environmental issues with horticultural societies and like-minded organizations by providing leadership and education.

We inspire Ontarians to promote and share gardening.

Our goals will:

  • Provide recognition, awards, and grants throughout Ontario.
  • Develop and support programs for all ages encouraging gardening, community beautification, environmental enhancement, and conservation.
  • Provide resources for horticultural societies.
  • Encourage the development of new horticultural societies.
