Pinus koraiensis 'Morris Blue' / Morris Blue Korean pine

Pinus koraiensis 'Morris Blue' is an upright, dwarf, tree-form of Korean pine with nice conical form, dense branching and long, silvery blue-green needles. After 10 years of growth, a mature specimen will measure 6 feet (1.8 m) tall and 40 inches (1 m) wide, an annual growth rate of 6 to 8 inches.

This cultivar originated as a seedling selected in the late 1980s by the Morris Arboretum, Philadelphia, Pennsylvania. 'Morris Blue' is one of eight selections made in 2020 for the popular ACS Collectors' Conifer of the Year program.
