This category contains the native flora of Illinois as defined by the World Geographical Scheme for Recording Plant Distributions. Taxa of the lowest rank are always included; taxa of higher ranks (e.g. genus) are only included if monotypic or endemic. Include taxa here that are endemic or have restricted distributions (e.g. only a few countries).
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

There are many different plant species and taxa that grow as a plant community in these alpine tundra. [1] These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [2]
The Illinois List of Endangered and Threatened Species is reviewed about every five years by the Illinois Endangered Species Protection Board (ESPB). [1] To date it has evaluated only plants and animals of the US state of Illinois, not fungi, algae, or other forms of life; species that occur in Illinois which are listed as endangered or threatened by the U.S. federal government under the ...
The native flora of the United States has provided the world with a large number of horticultural and agricultural plants, mostly ornamentals, such as flowering dogwood, redbud, mountain laurel, bald cypress, southern magnolia, and black locust, all now cultivated in temperate regions worldwide, but also various food plants such as blueberries ...
Because of the cold weather it is hard for plants to grow. Frozen ground covers most of the polar regions for the majority of the year. Permafrost reaches a thickness of 600–1,000 m (2,000–3,300 ft) deep. Large amounts of permafrost can lead to poor water drainage. Due to the permafrost the water in the soil remains frozen for most of the year.
