Noteworthy Characteristics
Swiss stone pine or arolla pine is native to mountain areas in central Europe from the Alps to the Carpathians. It is a slow-growing, medium-sized pine with a narrow pyramidal shape in its youth, gradually becoming rounded and more open as it matures. It typically grows 30-40’ tall in cultivation, but will grow to 100’ tall in the wild in its native habitat. Soft, dark green needles (2-5” long) appear in bundles of five. Short-stalked, oblong cones (to 2.5” long) are greenish purple when young, maturing to purplish-brown. Cones never open. Cone seeds are edible. The pine nuts consumed as food in Europe primarily come from the stone pines, namely, this species and P. pinea (Italian stone pine).
