Picea glauca


White spruce


Pinaceae (Pine Family)



Picea glauca (White spruce)
Makin, Julie
White spruce is a conical evergreen, up to100 or more ft. tall, with compact, regular branching. The lower branches sweep the ground and bear whitish-green needles. Small cones are concentrated in the upper crown. Tree with rows of horizontal branches forming a conical crown; smaller and shrubby at tree line.

This is the foremost pulpwood and generally the most important commercial tree species of Canada. As well as providing lumber for construction, the wood is valued for piano sounding boards, violins, and other musical instruments. White Spruce and Black Spruce (Picea mariana) are the most widely distributed conifers in North America after Common Juniper (Juniperus communis), which rarely reaches tree size. Various kinds of wildlife, including deer, rabbits, and grouse, browse spruce foliage in winter.
