A close relative of eastern white pine (Pinus strobus), this medium to tall evergreen tree inhabits the mountains of western North America. It is the state tree of Idaho.
The long, supple, blue-green needles of this pine occur in bundles of five on reddish-brown, hairy branchlets that age to deep brown or gray. In spring, trees produce tiny male cones and large, cylindrical, often curved female cones near the branch tips. The clustered, dangling female cones are sheathed with fleshy green scales that turn woody and buff-brown as they mature. Two-year-old female cones open their scales to release winged seeds, and are shed soon thereafter.
This stately, fast-growing, straight-trunked pine develops a narrow conical crown with short spreading branches. The gray to orange-gray bark is divided into several-sided plates.
This conifer favors full sun and moist, well-drained, humus-rich soil. It dislikes excessive heat, cold, or wind. It is worth considering for naturalistic plantings on large properties within its native range. (source: learn2grow.com)

| Useful Info | |
| Germination | 1. Place the seeds in a container with tepid water and soak them for 24 hours. Change the water and wait another 24 hours. 2. Put the seeds in a small plastic bag and cover with damp sand. Place the bag holding the seeds in the refrigerator for one to two months to stratify the seeds, which is preserving seeds in layers of moisture-laden peat, soil or sand. Check the sand and water as needed to maintain moisture. Don't allow the seeds to get soaked. 3. Fill small pots with compost. Place one or two pine seeds on top of the compost in each pot, then cover the seeds with a thin layer of sand. 4. Water the sand and compost to add moisture, then place the pots in a warm, sunny location. As the seedlings emerge and grow, the soil needs to remain moist, not wet. 5. Repot the pine trees into medium-sized pots in the fall. Grow them in the pots for the following season until they are large and strong enough for transplanting into the landscape. |
