The tree of life Viking
The Vikings had a tree of life called Yggdrasil also known as a world tree in Norse mythology and is translated as Odin’s Horse or Odin’s Gallows. It was the connection between nine worlds. It is an ash tree and therefore considered as holy. Symbolic creatures lived there like a dragon an eagle and stags. http://en.wikipedia.org/wiki/Yggdrasil
If we talk about making the trees in the world of the Vikings it was the hairs of Ymir who made trees. http://www.pitt.edu/~dash/creation.html
