The Siberian dwarf pine

A pine that would rather creep than climb. In the coldest parts of Asia it bends down under the snow — and that is how it survives the winter.

Pinus pumila
Shrub of 1–3 m
Needles in fives

Summary

The Siberian dwarf pine in brief

A low, creeping pine of mountain slopes and tundra in north-east Asia, built to get through the winter under a blanket of snow.

From eastern Siberia and Kamchatka to Japan, this pine rarely grows taller than a few metres. It forms vast, dense thickets in places where an ordinary tree would freeze or be blown over.

Its trick is flexibility: in autumn the branches lie down against the ground, where the snow covers them and insulates them from the icy cold. In spring they rise up again.

A five-needled pine

It belongs to the group known as white pines, with needles in bundles of five — like the Swiss stone pine and the western white pine.

Botanical: Pinus pumila
Origin: North-east Asia: Siberia, Kamchatka, Japan, Korea
Height: usually 1–3 m, creeping
Needles: in fives, 4–10 cm
Seeds: edible pine nuts
Wood: not a commercial timber

To be fair: as a timber, the dwarf pine counts for nothing — it never grows thick enough for boards. Its value lies in nature: it holds slopes together, and its seeds feed birds, squirrels and bears.

Recognising

How to recognise a Siberian dwarf pine

Siberian dwarf pinePinus pumila

Low and creeping

A shrub a few metres tall, often wider than it is high, with prostrate or ascending branches.

Needles in fives

Five needles per bundle, blue-green with pale stripes on the inner side.

Small cones

Purplish to brown cones with relatively large, edible seeds.

Built for snow

In winter the branches lie flat under the snow, protected from frost and wind.

From tree to plank

Why you can't saw boards from it

Too thin

The little stems stay thin and crooked; there is no usable board in them.

Firewood

Locally, the tough, resinous wood is used for burning.

Pine nuts

The seeds are harvested and eaten in Russia and Japan, just like those of other five-needled pines.

In the garden

As a rock-garden plant and in dwarf forms, you can sometimes find it in European nurseries.

An ecological keystone species

Where the dwarf pine grows, it is often the only shelter and the most important food source. In autumn, nutcrackers, squirrels and brown bears depend heavily on its seeds.

Quick answer

Frequently asked questions about the Siberian dwarf pine

How big does the Siberian dwarf pine grow?

Usually 1 to 3 metres, occasionally a little taller. It tends to grow outwards rather than up.

Why does it lie flat in winter?

Its branches bend down to the ground under the snow, where they are protected from the worst of the cold.

Are the seeds edible?

Yes. They are small pine nuts that are harvested and eaten in north-east Asia.

Does it produce usable wood?

No, the stems are too thin and too crooked for timber production.

The Siberian dwarf pine in perspective

Not a tree to saw boards from, but a masterpiece of adaptation to the cold.
