Eastern White Pine

Pinus strobus

Summary 6

Pinus strobus, commonly denominated the eastern white pine, northern white pine, white pine, Weymouth pine (British), and soft pine is a large pine native to eastern North America. It occurs from Newfoundland, Canada west through the Great Lakes region to southeastern Manitoba and Minnesota, United States, and south along the Appalachian Mountains and upper Piedmont to northernmost Georgia.

Like most members of the white pine group, Pinus subgenus Strobus, the leaves ("needles") are coniferous, occurring in fascicles (bundles) of five, or rarely three or four, with a deciduous sheath. The leaves are flexible, bluish-green, finely serrated, and 5–13 cm (2–5 in) long. The branches are spaced about every 18 inches on the trunk with five or six branches appearing like spokes on a wagon wheel. Eastern white pine is self-fertile, but seeds produced this way tend to result in weak, stunted, and malformed seedlings. Mature trees are often 200–250 years old, and some live over 400 years. A tree growing near Syracuse, New York, was dated to 458 years old in the late 1980s and trees in Michigan and Wisconsin were dated to roughly 500 years old.

Eastern white pine forests originally covered much of north-central and northeastern North America. Only 1% of the old-growth forests remain after the extensive logging operations from the 18th century to early 20th century. Old-growth forests, or virgin stands, are protected in Great Smoky Mountains National Park.

The Native American Haudenosaunee named the white pine the "Tree of Peace". It is known as the "Weymouth pine" in the United Kingdom, after Captain George Weymouth of the British Royal Navy, who brought its seeds to England from Maine in 1605
