Known for its delicious nuts, the Korean Pine tree can grow to more than 100 feet. It is pyramid-shaped with greenish-blue foliage and is native to Eastern Asia.
The blue and green bicolor needles appear in bundles of five on this tree and are 3-1/2 to 4-1/2 inches long.
Cones are not produced until the tree reaches five to seven years of age. The cones grow to about three to seven inches long and appear green but gradually turn purple, then brown when maturity is reached.
Pine nuts can be harvested in late September-early October. There can be up to 100 nuts in each cone.
The Korean Pine is a hardy tree that can withstand cold climates. It prefers well-drained sandy loam soil and can grow in acidic soil. Trees should be placed in semi-shaded areas, particularly in its first two years of growth. Hardiness Zone: 4-7.
