Pinus monticola Douglas ex D. Don
Western white pine
Synonym(s): Pinus strobus var. monticola
USDA Symbol: pimo3
USDA Native Status: L48 (N), CAN (N)
This 45-150 ft. evergreen forms a slender crown in thick stands or becomes more open and spreading when exposed. Branchlets are stout, bearing soft-textured, blue-green needles in groups of five. Bark is gray and smooth at first, becoming checked with flaking scales.
An important timber tree, Western White Pine is also a leading match wood, because of its uniformly high grade without knots, twisted grain or discoloration. It is one of the worlds largest pines; the champion near Medford, Oregon, is 239 (72.8 m) tall. White pine blister rust, caused by an introduced fungus (Cronartium ribicola), is a serious disease of this and other 5-needle white pines; a resistant strain is being developed.
