From WSU Clark County Extension:
Tall, straight, evergreen conifer growing to 100 feet or taller in height but staying relatively narrow in the crown to 30’. The crown is relatively open. In the upper portions of the tree the branches point upwards. The long straight trunk will often be devoid of limbs on the lower half of the tree.
 
Needles are 3”-4” long and arranged in bundles of 5. In addition, there are 6 white lines on the underside of the needles. Needles are held for 3-4 years before they are shed.
Male cones are small, yellow, and clustered near the tips of branches while female cones are larger (5”-12”), almost round, greenish pink in color and clustered near the tips of branches in the upper parts of the crown. Cones are pendulous. When mature they turn brown.

This species needs full sun. It can thrive on both dry as well as moist sites.
