This handsome but under-utilized pine from eastern Asia slowly forms a dense, somewhat conical, medium-sized tree.
The long, rather stout, dark-green to blue-green needles of this hardy evergreen conifer occur in bundles of five on fuzzy reddish-brown branchlets. In spring, trees produce tiny male and larger female cones near the branch tips. The erect, conical to ovoid female cones are green maturing to brown. They ripen their second year, falling from the tree without releasing their large edible seeds. This tree usually has a single trunk with scaly gray-brown bark.
This tough, adaptable, and beautiful tree favors full sun and well-drained, humus-rich soil. It does poorly in hot arid climates. With its attractive foliage and dense informal habit, this conifer is perfect as a specimen or for grouping in residential and public landscapes. (info 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.
