This medium to large evergreen tree from the Himalayas is most notable for its long needles, which cascade elegantly from its broad-spreading branches. The airy, drooping bluish green needles of this pine are held in bundles of five. The needles shimmer in the slightest breeze. In spring, trees produce tiny male cones and long curving female cones near the branch tips. The solitary or clustered female cones are green and erect when young and pale brown and pendent at maturity. They are often frosted with resin.
Conical and low-branched when young, this relatively fast-growing pine assumes a broad conical habit with age, retaining its lower branches when given adequate space. Its gray-brown bark becomes fissured and platy on older stems.
This beautiful pine favors full sun and well-drained, humus-rich soil. It dislikes excessive heat, cold, or wind. Its makes a striking specimen for parks and other large properties. Several cultivars are available, including variegated and cold-hardy selections. (source: learn2grow.com)

|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.
