The blue spruce (also known as a Colorado spruce) is a beautiful evergreen native to the Rocky Mountain region. However, it also grows in other cool regions, like the Appalachian Mountains in the East. It's density of branches, conical shape, and striking bluish-green color has made it a favorite in the Christmas tree industry. It is susceptible to some beetles and needle diseases but is used in landscaping and as windbreaks. It isn't usually used in the timber industry, because its wood is brittle and full of knots.
The Navajo ad Keres Native Americans have used the tree as a medicinal plant and for ceremonies. The twigs are supposed to bring good luck when given as gifts. It's been used as a folk medicine to treat colds, settle the stomach, and as a rub for rheumatism.
The tree grows rather slowly but can eventually reach heights over a hundred feet and live up to 600 - 800 years. It has a deep root system and doesn't blow down easily. It tends to retain its needles well and likes the higher elevations, where it's cool and humid. It was introduced to Europe late in the 19th century.
