This is a beautiful Pine. Twisted and silvery-blue needles on a Large growing selection putting on one foot plus per year. Its cones are said to be 'as large as a man's hand' and it's nuts are the most commonly used "pine nut" in cooking as with (any) selection of species Korean Pine. A superb and handsome selection with pyramidal growth.

(Jacobson, 'North American Landscape Trees') notes that 'This cultivar at least in Europe is sometimes sold as 'Glauca' ' - which is an incorrect or synomous name for this tree. 'Discovered in Germany in 1977' (Jacobson). A must for any collector.
