...very exuberant on the mountains of the more northern parts of Hungary. The roots generally run, it seems, in an oblique or subhorizontal direction; they are long, thick, and hard, clothed above ground with a brownish bark, shooting often to a considerable extent quite bare of earth.
PlantList lists it as a synonym of Pinus mugo Turra.
I purchased a 1-gallon plant from Lowes in March 2012 and planted it in a large pot with no bottom to give it good drainage in the Turret Front Garden.
