Eastern White Pine Identification: 5 Soft Needles

Eastern white pine is identified by its needle bundles. Davey Tree states that it is the only pine in the East with five needles per bundle. Pull one bundle and count: five soft, flexible, bluish-green needles means eastern white pine across nearly all of eastern North America.

The other northeastern pines hold fewer needles. The Northeastern Lumber Manufacturers Association (NELMA) points out that red pine and jack pine have bundles of two and pitch pine has bundles of three. Wikipedia notes eastern white pine occasionally has a bundle of three or four, so count several.

From a distance, NELMA describes the tree as bluish-green with a feathery look, and notes it sheds all but the current year's needles each fall. Inner needles turning yellow and dropping in autumn is therefore expected, not in itself a sign of disease.

Three more features confirm it:

• Cones: long, narrow and gently tapered, with scales that are not sharp or prickly (NELMA). Davey gives 3 to 8 inches; Wikipedia gives 8 to 16 cm. Davey notes cones take two to three years to mature and a tree is typically 20 to 30 years old before it produces them.
• Bark: smooth and greenish-gray on young trees; on mature trees reddish brown with scaly ridges broken into irregular shapes (NELMA). Davey describes mature bark as 1 to 2 inches thick with broad, darker ridges.
• Branch whorls: NELMA explains the tree adds one whorl of branches each year just below the top bud, so on a young, open-grown tree you can estimate age by counting whorls up the trunk. Lower whorls die and fall off in shade, so the count only works on young trees.

The comparisons people most often need:

• Pitch pine: three needles per bundle, green to yellowish-green and never bluish; stout oval cones, some staying closed until a fire. It grows in harsh, exposed places. White pine has five bluish-green needles, much longer and narrower cones that all open when ripe, and grows on richer sites (bplant.org).
• Red pine: two needles per bundle, 4 to 6 inches, that snap cleanly when bent; bark in broad, flat reddish plates (Tree Identifier).
• Western white pine (Pinus monticola): also five needles, but it grows in the mountains of the Northwest. Wikipedia notes it has larger cones, 12 to 32 cm, needles that last 2 to 3 years instead of 1.5 to 2, and a denser, narrower shape.
• Eastern hemlock: the Vermont Land Trust notes white pine bark resembles hemlock bark but is darker and thicker. Hemlock has short single needles, not bundles.

In lumber yards, "white pine" and "yellow pine" are two different groups. The Wood Database lists eastern white pine at 380 lbf Janka hardness and 25 lb per cubic foot dried, pale and even-textured. Longleaf pine, one of the southern yellow pines, is 870 lbf and 41 lb per cubic foot, reddish-brown heartwood, with sharp contrast between earlywood and latewood in each ring. Wikipedia lists loblolly, longleaf, shortleaf and slash pine as southern yellow pines. NELMA describes white pine lumber as light, workable and straight, with little shrinking and swelling.

Davey Tree lists the common downsides of eastern white pine as a landscape tree:

• White pine blister rust, an introduced fungus (Wikipedia names it Cronartium ribicola)
• White pine weevil, which Wikipedia also lists among the main threats
• Rust and root rot, and poor growth in overly wet soils; Davey notes it prefers acidic, well-drained soil
• Size: Davey gives up to 80 feet tall and 40 feet wide in landscapes, so it needs room

If branches or the top leader suddenly die back, photograph the damage and ask your county extension office or an arborist before treating anything.
