Pinus koraiensis 'Silveray' is a large growing, upright, narrowly pyramidal selection of Korean pine with beautiful, silver-blue, long, twisted needles - it is a very handsome plant. Typical rate of growth in most areas is 10 inches (25 cm) per year, resulting in a striking, lush pine tree, 8.5 feet (2.5 m) tall and 4 feet (1.2 m) wide after 10 years in the landscape.
ACS member, Ken Church says, "yes it is a zone 3 plant! I have had one for a couple of years in Winnipeg, Manitoba, Canada. It suffered during it's first winter but has done well ever since with no winter die back."
Hermann A. Hesse nursery, Germany originally distributed this cultivar under the name P. koraiensis 'Glauca' in the early 1970s. In 1978, F.J. Grootendorst nursery of Booskoop, The Netherlands, renamed it 'Silveray' in 1978 presumably to resolve the conflict of using a Latinized cultivar name after 1959.
