Celebrating Ottawa Gardens Since 1892
Welcome to the Ottawa Horticultural Society
Whether you’re a seasoned gardener, a curious beginner, or simply someone who enjoys the beauty of plants, we’re glad you’re here.
At the Ottawa Horticultural Society (OHS), we believe gardening is more than a hobby, it’s a way to connect with nature, build community, and nurture well-being. Since 1892, we’ve been bringing people together to share knowledge, swap plants, and celebrate the joy of growing.
Discover our Mission
Since 1892, the Ottawa Horticultural Society has been dedicated to promoting gardening knowledge and environmental stewardship. Our mission is to inspire and educate the community about the joys and benefits of gardening. Meet our passionate board members, learn about our affiliations with the Ontario Horticultural Association, and discover our esteemed patrons, including the Governor General and the Mayor of Ottawa.
