Concolor fir, is native to the western United States and may reach sizes of 130-150 ft. in height and 3 to 4 ft. in diameter. The oldest white firs may occasionally reach 350 years of age. It produces a spire-like crown with a straight trunk. On older trees, the lower one-half to one-third of the crown is often free of branches. Leaves (needles) are small and narrow and occur in rows. On upper branches, needles tend to be thicker and more curved than those on lower branches. Needles are usually 1/2 to 1 1/2 inch long, pointed or notched at the tip, bluish-green when young turning dull green with age. Typically, they are flat, without stalks. The bark on younger trees is thin, smooth, gray with numerous resin-bearing pockets. Older bark is thicker, reddish-brown to light gray and broken into irregular, flattened scales. Both male and female flowers (strobili) are found on the same tree. Pollination occurs in the spring and cones mature in one season. Cones are barrel-shaped, about 3 to 6 inches long, and mature in early fall. Cones are upright and generally disintegrate after seeds are shed. Good seed crops occur at 2- to 4-year intervals. White fir is tolerant of a considerable amount of shade. Its best growth is on moist loamy soils, but may often be found on dry, thin soils. The species seldom occurs in pure stands but grows in association with numerous other species depending on location and elevation. White fir is commonly found with Douglas-fir, sugar pine, ponderosa pine, and red fir. White fir is severely damaged by mistletoe. Leaves of white fir are often attacked by spruce budworm and Douglas-fir tussock moth. Bark beetles may also be a serious problem in some areas. As a Christmas tree, white fir has good foliage color, a pleasing natural shape and aroma, and good needle retention.

Scotch or Scots Pine is an introduced species which has been widely planted for the purpose of producing Christmas trees. It is an extremely hardy species which is adaptable to a wide variety of soils and sites. As a Christmas tree, it is known for its dark green foliage and stiff branches which are well suited for decorating with both light and heavy ornaments. It has excellent needle retention characteristics and holds up well throughout harvest, shipping and display.

A magnificent sight of silver blue-green spruce. Rated one of the most popular evergreens. Colo-rado Blue Spruce, or blue spruce, is an attractive tree often used for Christmas trees or as ornamentals, particularly in the eastern United States and Europe. It is the official state tree of both Colorado and Utah. The species generally reaches a height of 65-115 feet at maturity with a diameter of 2-3 feet. It has a narrow, pyramidal shape and cone-shaped crown. As trees become older, they often take on a more irregular appearance. While blue spruce grows relatively slowly, it is long-lived and may reach ages of 600-800 years.

The Fraser Fir, Abies Fraseri, is a classy, tall, fir tree that has short dark-green needles with silver undersides. It is among the most classy of conifers. A great ornamental and Christmas tree because of its density and compactness. Fraser Firs will grow in most locations but must have good drainage. Fraser Fir is a medium-sized tree, 40 to 70 feet high and one to more than two feet in diameter.

This dense evergreen tree has wood that is light, soft, not strong and coarse-grained. It is grown extensively for Christmas trees in North Carolina, where it is ranked as the number one Christmas tree by the Christmas tree industry.

Douglas Fir is not a true fir and has been a taxonomic nightmare for those trying to settle on a genus name. After changing names on numerous occasions the present scientific name Pseudotsuga menziesii now uniquely belongs to Douglas fir.
To make things even more complicated two different varieties of the species are recognized. There is the P. menziesii var. menziesii, called coast Douglas fir, and P. menziesii var. glauca called Rocky Mountain or blue Douglas fir. The unusual cone is also unique with, forked, snake-tongue-like bracts extending from each scale. It has been transplanted successfully throughout most of the North American temperate zone.
Douglas Fir grows 40 to 60 feet and spreads 15 to 25 feet in an erect pyramid in the landscape. It grows to more than 200 feet tall in its native habitat. The Douglas Fir makes an attractive Christmas tree because the needles do not easily fall off.

Eastern White Pine is an excellent ornamental conifer and is also an important timber species. When well established, it has a rapid growth rate when young with long distances between the annual lateral branches. Its form is somewhat pyramidal when young and becomes broad with age. The 3­5" long needles found in bundles of five are thin and soft. Needle color varies from plant to plant and ranges from yellow green to blue green. It is often used for Christmas trees. Many birds, squirrels, chipmunks and mice feed on the seeds and soft needles. Inner bark of white pine is a preferred winter food of porcupine and deer browse the twigs.
