The Canadian flora is depauperate because of the near total glaciation event in the Pleistocene. Due to the vast area of Canada, a tree that is common in one area may be completely absent in another. In particular, many warm-temperate trees can only be grown on the mild Pacific coast (where gardens may contain additional species not listed here).
According to environment Canada the nation of Canada hosts approximately 17,000 identified species of trees, flowers, herbs, ferns, mosses and other flora. [1] About 3,322 species of vascular plants are native to Canada, and about 830 additional non-native species are recorded as established outside cultivation there. [2]
An endemic species is a plant only native to a certain area. Outside this area, unless spread naturally it is considered non-native, usually as a result of cultivation. Britain and Ireland have few endemic trees, most being micro-species of Whitebeam. But there are some interesting endemic trees nevertheless.
Below is a list of Canadian plants by genus. Due to the vastness of Canada's biodiversity, this page is divided. Many of the plants seen in Canada are introduced by either intentionally or accidentally. N indicated native and X indicated exotic. Those plants whose status is unknown are marked with a ?.
This is a list of countries that have officially designated one or more trees as their national trees. Most species in the list are officially designated. Some species hold only an "unofficial" status.
