Appearance

Appearance

Usually a small tree, 20–40 ft (6–12 m) tall, with a crooked trunk, heavy limbs, and an irregular, rounded crown that flattens with age.

Growth form

Twigs are stout and orange- to red-brown; buds are very resinous. Bark is dark red-brown to gray and breaks into scaly plates.

Leaves

Stiff, twisted, yellow-green needles, usually in bundles of two (occasionally three), about 1.5–3 in (4–7 cm) long, with sharp tips.

Fruit

Egg-shaped cones 1.5–3.5 in (4–9 cm) long sit directly on the branch, often in clusters. Each scale ends in a stout spine that curves upward.

Look-alikes

Where it lives

Typical habitats

• rocky ridges
• dry slopes
• mountain knobs and peaks

Range

Found only in the Appalachian Mountains of the eastern US, from central Pennsylvania southwest through West Virginia, Virginia, North Carolina, and Tennessee to the far northeast corner of Georgia. A few outlying stands grow on isolated Piedmont peaks.

Preferred conditions

Dry, rocky slopes at about 980–5,770 ft (300–1,760 m). It usually grows as scattered trees or small groves rather than large forests.

Life cycle

Reproduction

Saplings can start bearing cones at about 5 years old.

Seed dispersal

Many cones are serotinous and can hang on the tree for 15–20 years, opening when heated by fire.

Growing it

Care

Occasionally planted as a native ornamental for dry, rocky, well-drained sites in full sun (USDA zones 5a–7b), though it can be hard to find in nurseries. Its wood has little timber value.

Conservation

IUCN Red List

LCLeast Concern·Low risk of extinction

Status

Secure to apparently secure across most of its range, but considered vulnerable in Georgia and critically imperiled in New Jersey.

Threats

Seedlings need regular disturbance to get started. Since fire suppression began around 1950, regeneration has declined in some stands as oaks and beech take over.
