they tend to be spruce or fir in our area. Is this for an exam? if so good luck.

The "classic" Christmas tree of old in this country is the Norway Spruce (Picea abies), though there are three species of Fir, genus Abies such as the Caucasian Fir (Abies nordmanniana) for example that have become popular of late because of their needle retention. The other two Firs being the Noble Fir (Abies procera) and the Fraser Fir (Abies fraseri).

i knew some one would know which ones specifically. as long as its a nice shape i have never really noticed the variety/species. hanging my head in shame !!
