Japanese stone pine or Siberian dwarf pine is a member of the pine or Pinaceae family and is native to Eastern Siberia, north-east of Mongolia, north-east of China, northern Japan and Korea. It is very slow growing and reaches only about 3 m in height, often having branches that extend along the ground.

• Needles are in fascicles of 5, thick, stiff, 4–6 cm long, triangular in cross-section, blue-green to green with light undersides, needles often curved or arching. Branches are in annual whorls.
• Cones mature in 2 years and are up to 3–4.5 cm long, ovoid, with leathery, broad, rounded scales, slightly curved up margins; cones are purplish in spring, ripening to reddish brown by fall. They remain on the tree for several years.
• Bark is gray-brown and scaly.
• The glaucous or blue-needled cultivar of this tree, P. pumila ‘Glauca’, is popular for use in landscaping.
