Pinus koraiensis 'Nana' is a slow-growing, upright, tree-form of Korean pine with long, twisted, silvery Blue-green needles. At maturity, a specimen will grow to a height of 4.5 feet (1.5 m) with a 4 foot (1.3 m) spread, a growth rate of 5 to 6 inches (12.5 - 15 cm) annually.
The origin of this cultivar is speculative at best. One of the first known listings was by E.A. Cope Nursery, USA in 1986. In addition, it is possible that this plant is synonymous with Pinus koraiensis 'Dwarf Form' which Drew Kellerman presented to Iseli Nusery in 1980. However, unless it can be proven that either cultivar name was established prior to 1959, neither qualifies as being a legitimate cultivar name.
