The Blue Spruce is one of the most admired and widely known of all
North American evergreens. A mountain tree, it has been successfully
planted over most of the USA and throughout Europe. It is also known as
the Silver or Colorado Spruce and is part of the Pine family. A straight
growing tree with horizontal branches, its limbs droop slightly to form a
clustered appearance. It can grow to 115' in height and its needles are
blue-green, short (1/2- 1 1/2"), slightly curved, and very stiff and
pointy. The scientific name pungens comes from the Latin word meaning,
"to prick". The needles give off a pleasant, resinous smell when
rubbed between the fingers.
The papery cones of the Blue Spruce are 3-4" long, a light
chestnut color, and are the female "flowers" of the tree. In the
Spring, the scales of the cone expand to catch wind-blown pollen from the
male flowers, which are on the same tree but different branches. Soon
after being fertilized, the cones turn down and become pendulous.
The Blue Spruce is America’s favorite Christmas tree and is used
extensively in landscaping. It is also planted in reforestation efforts
and shelterbelts. During winter, varied birds and wildlife feed from its
needles, twigs and seeds and nest in its branches.
Natural Habitat of Blue Spruce: Rocky Mountains & the
Southwest often near streams. Best in fertile soil with abundant moisture.
Once established can withstand drought and temperature extremes.
