Ontario Wildflowers - Native Species

A list of Ontario Native Wildflower species found on this site, in order by the Common Name. The distinction of Native and Non-native species is sometimes not clearcut. For the purposes of this website various sources are used. Generally speaking, a species is considered to be non-native if it did not occur in the region prior to the arrival of Europeans. But there may be exceptions.

The distinction between Native and Non-native species is important because many Non-native species are invasive and alter the ecosystem of an area. They may crowd out native plants. Animals, not being familiar with foreign plants, frequently will not use them for food or even shelter. So the impact of the Non-native species extends well past their simple presence in an area.
