(Blue-needled Whitebark Pine, Whitebark Pine)
This small dense evergreen tree comes from high altitudes in western North America. It is closely allied to limber pine (Pinus flexilis), which is sometimes sold under its name.
The stout, deep green to yellow-green needles of this pine are held in bundles of five toward the tips of long flexible branches. The needles have conspicuous white lines on their upper surface. In spring, trees produce tiny male cones and large scaly female cones on the previous year's growth. The egg-shaped,...

This small, very long-lived and slow-growing pine is perfectly adapted to dry, high altitude mountain communities throughout the western United States where soils are thin and moisture scant. A native of the high country of western Colorado, northern New Mexico, and northern Arizona, it is best known for its very long lifespan and the twisted, gnarled form of older specimens. Some specimens are more than 2000 years old. The most ancient bristlecone trees (approaching 5000 years old) belong to Pinus...

An exceedingly slow-growing, dense, conical selection of bristlecone pine, this cultivar was introduced by Sherwood Nursery, Portland, Oregon. It may be a selection of Pinus longaeva.
The stubby, stiff needles of this dwarf cultivar are borne in bundles of five that remain on the plant for many years, forming dense bottlebrush-like clusters at the ends of the branches. The foliage lacks the resinous white flecks typical of P. aristata. This cultivar grows extremely...
Most often represented in gardens by its drought-tolerant variety eldarica, this medium-sized evergreen tree comes from the eastern Mediterranean region.
The long, stiff, bright green needles of this pine occur in bundles of two. The needles crowd the outer branches, forming a dense crown. In spring, tiny male cones and larger female cones appear near the branch tips. The female cones - which diverge at right angles from the branches - persist for two years, ripening from green to...
(Eilar Pine, Mondell Pine)
This relatively fast-growing and drought-tolerant form of Calabrian pine is widely planted in California and the American Southwest. It is native to the Republic of Georgia.
The long, stiff, bright green needles of this evergreen conifer occur in bundles of two. The needles are not as crowded as those of most other Calabrian pines, resulting in a somewhat sparser crown. In spring, tiny male cones and larger female cones appear near the branch tips. The female cones - which diverge at sharp...

(Swiss Stone Pine)
A slow-growing tree from mountains of Europe and western Asia, Swiss stone pine is prized for its compact, symmetrical, upright form. The semi-dwarf cultivar 'Chalet' has blue-green needles and a narrowly conical habit.
The long, stiff, blue-green needles of this evergreen conifer occur in bundles of five. In spring, trees produce tiny male cones and larger female cones near the branch tips. Female cones persist 3 years, maturing to purple-blue and then brown. Mature female cones are the size...

(Mexican Stone Pine)
Famous for its edible nut-like seeds, this small evergreen tree from Mexico and the Southwest United States is well suited for desert gardens.
This cold-hardy pine bears short, curved, dark green needles in bundles of three. In spring, trees produce tiny male cones and ovate female cones on the previous year's growth. The female cones are covered with fleshy green scales that become woody and reddish-brown as they mature. Two-year-old female cones release large edible seeds before falling...
(Alabame Pine, Sand Pine)
This small to medium evergreen tree occurs in acid sandy soil from southern Florida to southeastern Alabama.
This short-lived, gangly pine has twisted, rather short, dark green needles in bundles of two. In spring, trees produce tiny male cones and egg-shaped female cones on the previous year's growth. The female cones are covered with fleshy green scales that become woody and yellowish-brown as they mature. The scales of 2-year-old female cones open in summer to release winged seeds. The female...
(Japanese Red Pine, Tanyosho Pine)
This selection of Japanese red pine has a spreading canopy and open-headed habit at maturity that are more sculptural than its parent species, which is native over a huge range from mainland China to Japan and Korea. In Japan, ‘Umbraculifera’ is an important part of the traditional garden. Unlike American pines, this tree has little drought resistance and prefers moderate temperatures and regular rainfall. Its coastal origins suit it to endure persistent ocean winds.
This pine bears its needles...

An important source of timber and pulpwood within its native range, this medium to large evergreen tree occurs on sandy and rocky sites from southern New York to Florida to the lower Midwest.
The relatively short, soft, dark green needles of this pine occur in bundles of two or sometimes three. They are borne toward the tips of slender, horizontal to drooping branches. In spring, tiny male cones and relatively small female cones appear near the branch tips. The prickly, conical female cones...
