Info

You have a FIR. Your mystery sample is a WHITE FIR or CONCOLOR FIR. White fir do not begin producing cones or seeds until the tree is about 40 years old. The white fir makes a beautiful Christmas tree and it is important to many species of wildlife. (The fir is just one of several kinds of conifers that have flat needles. Others include hemlock, douglasfir, and baldcypress.) Please take your tree sample to your teacher and he/she will let you know if you have correctly identified your mystery tree.
You have a COLORADO BLUE SPRUCE. Because of its beautiful blue-green needles and adaptability to different soils and climates, the Colorado blue spruce is one of the most popular evergreens for ornamental planting. (This is just one of a number of spruce species in the United States.) Please take your tree sample to your teacher and he/she will let you know if you have correctly identified your mystery tree.
