The Ottawa Orchid Society (OOS) was founded in 1978 to promote and assist in every way the knowledge, appreciation, culture, study, development, improvement and conservation of orchids. Members come from all walks of life and are very happy to share their knowledge and experience.


The Ottawa Orchid Society is affiliated with the Canadian Orchid Congress (COC) and with the American Orchid Society (AOS). Through these affiliations, the Society is able to obtain world-class speakers for regular meetings. We meet the third Sunday of every month, except April, June, July and August, from 1:30 p.m. to about 4:00 p.m. Please click here for more details and our plans during the COVID-19 pandemic.


A Board of Directors manages the affairs of the Society, with elections held every two years in accordance with the Society’s formal Constitution. The first Ottawa Orchid Society plant to receive an AOS award was in May 1979.  For more information and a detailed history of the Ottawa Orchid Society, please visit our Society Organization page.
