The flora of Canada is quite diverse, due to the wide range of ecoregions and environmental conditions present in Canada. From the warm, temperate broadleaf forests of southern[Ontario to the frigi Arctic plains of the Northern Canada, from the wet temperate rainforests of the west coast to the arid deserts, badlans and tundra plains, the biodiversity of Canada's plants is extensive. About 4,100 species of vascular plants are Indigenous (ecology)|native to Canada, and about 1,200 additional non-native species are recorded as established outside Plant cultivation|cultivation there.
