Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bedding plants which are sown in heat in winter or early spring, and planted outside after all danger of frost has passed.
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.

Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Plants have evolved numerous strategies to deal with cold air, frozen soil, and in the coldest of conditions, lack of water through the winter. Brr! Here are 4 ways plants, trees survive frigid ...
“When choosing plants for your containers that you intend to stay there over the winter, select plants that are zoned for at least one–ideally two–hardiness zones colder than your region to ...
On the 2012 Plant Hardiness Zone map, Greater Columbus (and a good portion of the rest of Ohio) was in Zone 6a, where the average lowest temperature ranges from -10 to -5 degrees Fahrenheit.
It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F (−1.1 to 4.4 °C). Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale.
The South Temperate Zone, between the Tropic of Capricorn at 23°26′09.7″ S and the Antarctic Circle at 66°33′50.3″ S, covers 25.99% of Earth's surface. The South Frigid Zone, from the Antarctic Circle at 66°33′50.3″ S and the South Pole at 90° S, covers 4.12% of Earth's surface. Earth's climatic zones
