Pinus pumila, the Siberian dwarf pine, dwarf Siberian pine,[1][3] dwarf stone pine,[1] Japanese stone pine,[3] or creeping pine,[4] is a tree in the family Pinaceae native to northeastern Asia and the Japanese isles. It shares the common name creeping pine with several other plants.

Description

The Siberian dwarf pine is a coniferous evergreen shrub ranging from 1–3 metres (3–10 feet) in height, exceptionally up to 5 m (16 ft), but may have individual branches that extend further along the ground in length. In the mountains of northern Japan, it sometimes hybridizes with the related Japanese white pine (Pinus parviflora); these hybrids (Pinus × hakkodensis) are larger than P. pumila, reaching 8–10 m (26–33 ft) tall on occasion.[citation needed]

The leaves are needle-like, formed in bundles of five and are 4–6 centimeters long. The cones are 2.5–4.5cm long, with large nut-like seeds (pine nuts).[5]

Distribution

The range covers the Far East, Eastern Siberia, north-east of Mongolia, north-east of China, northern Japan and Korea.[3] Siberian dwarf pine can be found along mountain chains, above the tree line, where it forms dense, uninterrupted thickets; it also grows on the headlands above the Okhotsk and Bering Seas, Tatarsk and Pacific coast (the Kurils).[citation needed]

P. pumila grows very slowly. It can live up to 300 and, in some instances, 1,000 years.[6]

Ecology

The seeds are harvested and dispersed by the spotted nutcracker (Nucifraga caryocatactes).

P. pumila has highly flammable needles, branches, and cones and readily carries crown fires, especially where it grows continuously across local landscapes.[7] It has serotinous cones that release seeds following fire[8] facilitating its recovery following severe fires caused by lightning strikes and other causes.[7][9]

Cultivation

This plant is grown as an ornamental shrub in parks and gardens. The cultivar P. pumila 'Glauca' has gained the Royal Horticultural Society's Award of Garden Merit.[10]
