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.
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.
The White Spruce is excellent for ornaments; it's short, stiff needles are ½ - ¾ in. long and have a blunt tip. They are bluish-green - green in color, but have a bad aroma when needles are crushed. They have excellent foliage color and have a good, natural shape.
