Pinus pumila, commonly called dwarf Siberian pine, also commonly known as Japanese stone pine, is a shrubby sometimes prostrate pine that is native to eastern Asia. It grows to 1-9′ tall. Blue-green needles (to 3″ long) in bundles of five. Immature purple-violet seed cones (1-2″ long) mature to reddish brown. Similar in appearance to Pinus cembra, and was at one time considered to be a form of that species.
