Eastern White Pine, Pinus strobus, is a large pine native to eastern North America, occurring from Newfoundland west to Minnesota and southeastern Manitoba, and south along the Appalachian Mountains to the northern edge of Georgia.

It is occasionally known as simply White Pine, Northern White Pine, or Soft Pine. It is also known as Weymouth Pine,[1] especially in Britain. In addition, this tree is known to the Haudenosaunee Native Americans as the Tree of Peace.

Like all members of the white pine group, Pinus subgenus Strobus, the leaves ('needles') are in fascicles (bundles) of five (rarely 3 or 4), with a deciduous sheath. They are flexible, bluish-green, finely serrated, and 5-13 centimeters (2–5 in) long, and persist for usually about 18 months.

The cones are slender, 8-16 centimeters (3–6 in) long (rarely longer than that) and 4-5 centimeters (1.5–2 in) broad when open, and have scales with a rounded apex and slightly reflexed tip. The seeds are 4-5 millimeters (3/16 in) long, with a slender 15–20 mm (3/4 in) wing, and are wind-dispersed. Cone production peaks every 3 to 5 years.

Mature trees can easily be 200 to 250 years old. Some white pines live over 400 years. A tree growing near Syracuse, New York was dated to 458 years in the late 1980s and trees in both Wisconsin and Michigan have approached 500 years in age.
