Fruit and Nut Trees – Fruit Bearing Plants

Korean Pine, Pinus koraiensis, is an evergreen, tall growing tree, getting to a height of more than 30 meters and up to 2 metres trunk diameter with a loose pyramidal form, medium growth rate and a very ornamental appearance. The Korean pine is indigenous to eastern Asia, Korea, Manchuria, far eastern Russia, and central Japan.

Pinus koraiensis leaves (needles) are dark green with coarse-toothed margins, on average 8cm long , clustered together in groups of 5 persisting on the tree for 3 years. Flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) with no ornamental value.

Korean Pine Nuts

Cones are reasonably long (10-15cm), resinous with thick leathery scales. They average 60 edible nuts (seeds) each and filled up nuts average about 90%. Seeds are extensively harvested and sold as pine nuts, particularly in north-eastern China; it is the most widely traded pine nut in international commerce. The nut oil contains 11.5% of the unusual fatty acid pinolenic acid. Production starts at 7 – 8 years of age on the average.

The Korean pine is comparatively maintenance free, with no pests. It thrives in a light well-drained sandy or gravelly loam but it is adaptable to most soil types and pH as long as they are well-drained. It prefers full sun but light shade is ok. Korean Pine is a popular ornamental tree in parks and large gardens wherever the climate is cold. It is fairly drought tolerant.

Korean Pine Propagation Methods

Plant propagation is by seed with no pregermination demands. Plants have a very sparse root system and the sooner they are planted into their permanent positions the better they will grow if started in pots. Pinus koraiensis is a member of the family Pinaceae the genus Pinus.
