Pinus koraiensis glauca, Blue Korean pine USDA H4-hardy, a bit more bluey than the straight specie, faster growing, (as grafted on a rootstock more suitable for UK climate)
6-13cm needles, green on the underside with blue-white, conspicuously, the other. Yellow pollen cones. All in all a very pretty, fluffy foliaged medium size tree reaching 20-30m
