The European silver fir (abies alba) gets its name from the silvery color effect caused by the white stripes along the undersides of the needle like leaves. It is a common tree used for Christmas trees in Europe and North America, prized for its color, shape and for the fact that its needles are not excessively sharp.

The branchlets also form a geometric pattern (common to most true firs)
