Strobus strobus (L.) Small, nom. inval.
Pinus strobus L. Eastern white pine, white pine
Eastern white pine is a widespread native of North America. The soft, lightweight, easily worked wood has many applications. Trees often reach 250 years in age, with the oldest approaching 500 years. Identification: Trees typically reach 50-80′ (15-24 m) high, and up to 120′ (36 m). Young trees are conical in shape, but older trees often lose lower branches and become less evenly shaped. Bark on younger trees is smooth and gray; on older trees it takes the form of gray or reddish rounded scales. Leaves are blue-green evergreen needles 3-5″ (7.6-12 cm) long, in groups of 5. Needles are thinner (less than 1/32″ (1 mm)) than those of other species of pines. Male flowers are yellow, while female flowers are light green; both are inconspicuous. Cones are 5-10″ (12-25 cm) long, oval or cylindrical in shape, up to 1½″ (3.8 cm) wide. For further information, see the Pinus comparison tables. Online References:
