Plant Life

Tundra does not have many plants since it's frozen most of the time. The only plants you can find there, are usually really small plants such as Arctic Moss, Bearberry and Small willow.

 Arctic Moss
Genus: Calliergon
Species: gigantium

 Source 
 When Calliergon gigantium is not growing, it stores nutrients so new leaves can be made quickly next spring.  It's adapted to the strong winds because it grows near to the ground. Since it can grow under water it is protected from the drying winds and cold, dry air of the frozen tundra. Its long life and slow growth are adaptations to the cold and the short growing season.

Arctic Willow

 Common Name: Rock Willow
 Genus: Salix
Species: arctica

Salix arctica is also known as Arctic willow or Rock willow. It's mainly found in the North American tundra. In it's strongest growth season the Salix arctica forms a pesticide to keep insects like the Arctic woolly bear away. It's also adapted to the permafrost by growing a shallow root system. The leaves of the Salix arctica are also adapted to the cold weather by growing long fuzzy hairs.


Bearberry
Common Name: Bearberry, Foxberry and Kinnikinic
Genus: Arctostaphylos
Species: uva-ursi

Bearberry is sometimes known as Foxberry. It is commonly found in dry, non-nutrient soils such as sands, soils on rock outcrops and shallow soils. Since Bearberry is a low growing plant it can stay out of the wind chill. Its fine silky hairs also keep it warm. Its leathery leaves also helps it to survive in tundra areas.
