Save Ontario’s Seed: On August 23, 2017 the Ministry of Natural Resources and Forestry announced the closure of the Ontario Tree Seed Plant. Since 1923, this unique facility and its staff have provided expertise and best practices to ensure that high quality, source-identified seed is translated into successful planting projects that preserve Ontario’s biodiversity, protect our water, air and soils, and support jobs in the nursery, forestry and wood manufacturing sectors. For more info and to download a letter to send to the Ontario government, go to the Forest Gene Conservation website. Online petition can be found here.

Our History

NANPS was founded in 1985 by a small group of dedicated conservationists as the Canadian Wildflower Society. As our American membership grew and acknowledging that plants don’t recognize political boundaries, we changed our name to the North American Native Plant Society in 1999. In 1985 we founded North America’s foremost native plant magazine: Wildflower. The original magazine ceased publication in 2005, but it’s name lives on under the editorship.


NANPS currently owns two conservation properties: Shining Tree Woods in the Carolinian zone of southern Ontario and Zinkan Cove on the west shore of the Bruce Peninsula on Lake Huron. Both properties offer unique gifts and distinct challenges. Maintaining conservation lands is a prodigious responsibility but the rewards are equally great. While relatively small, NANPS properties are home to a number of rare flora and fauna and we are justifiably proud of our efforts to protect them.
