Needles (2.3-3" long) in fascicles of 5, densely crowded at branch ends and persisting 5 to 6 years. 3-4 waxy lines on each surface, with the effect that needles appear glaucous blue at times. Stem is shining green, thickish, but very flexible and can even be tied in knots.
Large taproot makes it difficult to transplant once established. Generally low maintenance with few problems, but is susceptible to White Pine Blister Rust. Decaying needles acidify soil beneath (to about pH 4.5), which suppresses growth of other plant species.
