Who we are

The mission of the Ottawa Horticultural Society is to cultivate an interest in plants and gardening in order to create a beautiful community.

The OHS as we know it today has a long history.  It started in 1892 and is a non-profit society open to all gardeners who enjoy sharing their enthusiasm and knowledge of gardening.   We have over 300 members, and our activities include regular meetings with speakers, community projects and competitions.

We are honoured to have  Her Excellency the Right Honourable Julie Payette, C.C., C.M.M., C.O.M., C.D., Governor General of Canada as patron of the society, and to have His Worship, Mayor Jim Watson as Honorary President.

Membership is $15 for an individual or $20 for a family and includes benefits such as an informative newsletter three times per year, tours of members’ gardens, and discounts at select local nurseries.

At the provincial level we are affiliated with the Ontario Horticultural Association, District 2.

The OHS is governed by its Constitution and By Laws.

Monthly Open Meetings

Monthly meetings are normally held on the fourth Tuesday of the month from September through June and feature a guest speaker on a gardening related topic.  These meetings are open to the public and are held at the Tom Brown Arena, 141 Bayview Road (at Scott).  Check out the events page to find the details of upcoming meetings.

Plant Sales

The OHS holds several plant sales each year, which provide a chance to buy plants that members have grown in their own gardens.  A good source of plant material suited to the local Ottawa conditions! In 2014 the OHS will once again be participating in ohsplantsalethe Friends of the Farm Rare and Unusual Plant Sale in May, holding its own plant auction and sale in late May, and finally the Old Ottawa South Porch Sale in early September.    The details of sales are updated on the events page as they are finalized.

Community Planting

As part of its mission to create a beautiful community, the OHS usually takes on one or two community projects each year, using funding generated by memberships and plant sales.  Over two or three weekends, members volunteer their time to work on a gardening project in support of a local organization.  Check out the community planting page for more information.

Members Only Events

OHS members can participate in additional activities such as shows, the photographic competition, and garden tours.
