Nodding Trillium (Trillium cernuum)

Welcome to the Ontario Wildflowers website!
Your "online field guide" to Ontario's wildflowers

This website is all about wildflowers and plants that grow in Ontario (Canada).
If you're not from Ontario, don't go away! Most of the plants featured on this website grow elsewhere in eastern North America, and many grow elsewhere in the world.

Please note that this website is not complete
I have hundreds of wildflower photos & species that I am adding to the site
