Plant#2

The arctic willow is 15-20 cm in height. It has many different shapes, but sometimes has long trailing branches that root where they touch the surface. Salix arctica has made many adaptations to the cold climate of the North American tundra. In its strongest growth season the Salix arctica forms a pesticide to keep insects like the Arctic woolly bear away. It has also adapted to the permafrost by growing a shallow root system. The leaves of the Salix arctica have also adapted to the cold weather by growing long fuzzy hairs. The Tundra is a delicate place where tire tracks can last for years. The Arctic willow has adapted well in these frigid non-fertile conditions.
