Noteworthy Characteristics

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.

Genus name comes from the Latin name for pines.

Specific epithet means dwarf.

Problems

This pine can be difficult to grow well in the St. Louis area because of soil and climate. It is susceptible to tip blight, rusts and rots. Pine needle scale can be a serious problem in some areas. Sawflies, moths and borers may appear.
