Pinus Nigra Grows a dense, stout pyramid with a uniform crown. Branches are in regular whorls and with age the tree forms a broad and flattened top. The needlelike leaves occur in bundles of two, are 4 to 6 inches long, are stiff and sharp pointed, and of a light green color. The egg-shaped cones are 2 to 3 inches long and 1 to 1-1/4 inches wide. The cones open during the late fall and early winter.

Pinus Sylvestris The Scotch pine is a thick, hardy tree that holds its needles well over the holidays. Trees grown on a farm respond well to pruning and grow in well-rounded conical shapes with few breaks in the foliage.
The color of a Scotch pine is variable; some trees may be blue-green while others are yellow-green. The needles appear in clusters of two, are usually twisted and are about four to eight centimeters long. The bark on the upper portion of the stems is orange or orangeish-brown and is smooth to the touch. Closer to the trunk it is a greyish or reddish-brown and the trunk is often fissured in scaly plates. The cones grow both singly and in groups of two to three and are up to eight centimeters long. They are usually yellow-brown and contain tiny prickles on the cone scales.

Pinus Strobus Many people think that the graceful White pine is the most beautiful of all Christmas tree varieties, even though its soft needles make it difficult to decorate. In the wild it can reach diameters of 15 meters and heights of 45 metres.
The needles are five to twelve centimeters long, are soft and flexible and appear in bunches of five. The bark is smooth to the touch and is greyish-green near the tips of the branch, becoming rougher and a darker grey-brown closer to the trunk. The cones mature in the fall and drop from the tree during the winter. Usually eight to twenty centimeters long, and three centimeters in diameter, the cones contain 50 to 80 scales arranged in five spiral rows.
