Summary

Overview
There are between 35 and 50 species of spruce. They grow exclusively in the northern hemisphere in temperate and boreal (an ecosystem with a subarctic climate) regions. The most popular in the UK is the Norway spruce (aka a Christmas tree).
A key identifier of spruce is the fact that the needles grow in isolation on little wooden pegs (see gallery, and conifer identification flowchart (link below)). Also, the cross section of the needles is square or triangular and I can roll easily in your fingers.
Space is being used as timber for a long time. Additionally, issued in food and medicine (It has high volumes of vitamin C).
English no spirits literally means "from Prussia" in middle English. (For those that don't know (I didn't) Prussia is a former state in northern Europe)
As a little bit of bonus knowledge a spruce tree in Sweden is said to be the oldest living tree. Google it man.
