White Spruce Most spruce
needles are four-sided, stiff, and less than one
inch long, 2.5 centimeters to be exact. Woody,
peglike projections help join the needles to the
twigs. Spruce trees grow tall and most are shaped
like pyramids. Some grow as tall as one hundred and
fifty feet, specifically the white spruce. The
spruce tree is an evergreen color but specific
types of spruces, the black spruce for example, are
named for the color of their bark and foliage.
The
needle-like leaves attached to the common spruce
trees are used to hold in moisture. The blue spruce
is widely planted in yards because of its beautiful
silver-blue foliage. Some spruce
trees grow beyond the Arctic Circle, whereas others
can grow as far south as the Pyrenees
Mountains. by Leah E. 2000
