Pine Identification: Needles per Bundle, Cones and Bark

You can identify a pine by pulling one bundle of needles off a twig and counting them. Cornell Small Farms gives the rule that separates pines from every other conifer: pine needles grow in clusters of 2, 3 or 5, and each cluster is called a fascicle. Spruces, firs, hemlocks and Douglas-fir hold their needles one at a time.

The count also splits pines into two working groups:

• Five needles: the soft or white pines. Cornell notes that on eastern white pine the papery sheath at the base of the bundle drops off in the first season.
• Two or three needles: the hard pines, such as red, jack and pitch pine, where Cornell notes the sheath stays on.

Nature Hills Nursery offers a memory aid: "white" has five letters, like white pine's five needles. The trick does not carry over to red pine, which has two needles, so treat it only as a starting point. Wikipedia notes that across all pines the count ranges from one to seven, but is generally two to five.

Count several bundles from different branches. A single bundle with an odd count is common, and Wikipedia notes eastern white pine rarely has three or four.

Once you know the bundle count, needle length and cone size narrow it to a species. These figures come from Tree Identifier's species guide unless noted:

• Two-needle: red pine 4 to 6 inch needles that snap cleanly, cones 1.5 to 2.5 inches; Scots pine 1.5 to 3 inch blue-green twisted needles; jack pine 1 to 1.5 inches, the shortest of the common two-needle pines; lodgepole pine 1 to 3 inches, yellow-green and twisted.
• Three-needle: ponderosa 5 to 10 inches with prickly 3 to 6 inch cones; loblolly 6 to 9 inches; longleaf 8 to 18 inches with 6 to 10 inch cones, the longest needles of the eastern pines; pitch pine 3 to 5 inches, stiff and twisted, and able to sprout branches directly from the trunk.
• Five-needle: eastern white pine 3 to 5 inches and soft; sugar pine with cones Wikipedia puts at mostly 4 to 20 inches, among the longest of any conifer; bristlecone pine 1 to 1.5 inches, densely packed.

A separating trick for two western three-needle pines comes from Wikipedia's Jeffrey pine article: the barbs on Jeffrey pine cone scales point inward, so the cone feels smooth when you run your palm down it, while ponderosa's point outward. The mnemonic is "gentle Jeffrey, prickly ponderosa."

Bark is useful on large trunks, and less useful on young trees, where most pines are smooth. Features the top guides describe:

• Red pine: broad, flat, reddish-brown plates (Tree Identifier).
• Scots pine: bright orange-brown bark on the upper trunk, which you can see from a distance (Tree Identifier).
• Ponderosa pine: large plates fitted together like puzzle pieces. Wikipedia notes the bark smells like vanilla if sampled from a furrow, though sources disagree on the scent.
• Eastern white pine: smooth and greenish-gray when young; on mature trees reddish brown with scaly ridges broken into irregular shapes (Northeastern Lumber Manufacturers Association).
• Longleaf pine: thick orange-brown plates (Tree Identifier).

Bark alone rarely settles a species. Use it to confirm what the needles told you, and see our tree bark identification guide for other trees.

Most "pine trees" people ask about turn out to be another conifer. Cornell Small Farms gives the feature that separates each one:

• Spruce: four-sided needles attached singly to small woody pegs (sterigmata) about 1 mm long, which stay on the twig after the needles fall. Crushed foliage smells pungent.
• Fir: flat needles, usually arranged in two rows along the sides of the twig, leaving a round pad when pulled off; cones stand upright; crushed foliage smells citrus-like. Balsam fir has resin blisters on young bark.
• Hemlock: very short needles, marble-sized hanging cones, and a leader that often droops.
• Larch: needles in clusters on short spur shoots, like a pine at a glance, but larch drops all its needles in autumn.
• Cedar and juniper: flattened, scale-like foliage rather than true needles.

If a tree has single needles rather than bundles, it is not a pine. See our hemlock tree identification page for that group.

Oregon has a mix of Pacific coast, Cascade and Great Basin pines. Going by the range given in each species' Wikipedia article, the pines native to Oregon include:

• Ponderosa pine: three needles, the Pacific form with needles 15 to 24 cm; egg-shaped cones 8 to 13 cm. A rare variety grows in the Willamette Valley.
• Lodgepole and shore pine (Pinus contorta): two needles 4 to 8 cm; cones 3 to 7 cm with prickles. Shore pine grows along the coast; the tamarack subspecies ranges from the Oregon Cascades south.
• Sugar pine: five needles 5 to 11 cm and very long cones; grows in the Cascade Range and Coast Ranges of Oregon and California.
• Western white pine: five needles 5 to 13 cm; long slender cones 12 to 32 cm.
• Whitebark pine: five needles 3 to 7 cm; cones that do not open on drying. It grows at high elevation and was listed as threatened by the U.S. Fish and Wildlife Service in 2022.
• Jeffrey pine: three needles 12 to 28 cm; from southwest Oregon south.
• Knobcone pine: three needles 9 to 15 cm; closed cones often stay attached to the trunk; from the mountains of southern Oregon south.

Pine lumber comes in two very different kinds, and a thumbnail test goes a long way. The Wood Database gives eastern white pine a Janka hardness of 380 lbf and an average dried weight of 25 lb per cubic foot, with even texture and a gradual change between the light earlywood and darker latewood of each growth ring. Longleaf pine, one of the southern yellow pines, measures 870 lbf and 41 lb per cubic foot, with an abrupt, high-contrast change between earlywood and latewood.

So a soft, light, evenly colored board is likely a white pine; a heavier board with sharp dark and light stripes on the end grain is likely a southern yellow pine. Wikipedia lists loblolly, longleaf, shortleaf and slash pine as southern yellow pines. The Wood Database notes white pine gives off a faint resinous smell while it is being worked, and Wikipedia describes pines generally as resinous trees.

For the app or an extension office, these shots answer most questions:

• One needle bundle held against your palm, with the needles spread so they can be counted
• A cone, whole, with something for scale
• The bark at chest height
• The whole tree from a distance, showing its shape

The bundle shot is the one that decides it. Photograph it and the app identifies it; use the needle count on this page to check the answer.
