Japanese White Pine
Native to (or naturalized in) Oregon:
- Conifer, evergreen tree, to 100 ft (30 m) tall, slender branches. Needles 2-8 cm long, 5 per cluster, slender, margin serrulate, green on outside, white on inside (ventral) surfaces. Cones solitary or in clusters, 5-10 cm long, 3-4 cm wide, nearly sessel (not stalked), opening widely, persisting 6-7 years. According to Jacobson (1996)....wild specimens have very slender 9 cm needles and grow as normal "white pines"...such trees are rarely seen in North America... the commonly cultivated form is ‘Glauca’ which has shorter needles, less than about 5.7 cm. The specimen shown here, although labeled Pinus parviflora, may in fact be P. p. ‘Glauca’.
