Known as ‘gran' in Norwegian, the Norway spruce shapes much of the country’s forest landscape, supports an important timber industry and remains a familiar sight at Christmas.

Few trees are more closely associated with Norway and the Scandinavian winter than the Norway spruce.

Its tall, pointed silhouette dominates forests across much of eastern and central Norway, while its timber has helped build everything from houses to furniture.

It is also the species chosen for one of Norway’s best-known international traditions: the enormous Christmas tree sent from Oslo to London every year.

Yet despite its name, the Norway spruce is not uniquely Norwegian. Its natural range extends across large parts of northern, central and eastern Europe.

Introducing the Norway spruce

The Norway spruce is known simply as gran in Norwegian. Its scientific name is Picea abies, and it belongs to the pine family.

It is Norway’s most economically important tree species. According to the latest figures, spruce accounts for 44% of the total volume of growing timber in Norway and more than half of the country’s annual forest growth.

Spruce wood is relatively light, easy to work and suitable for many purposes. It is widely used for structural timber, exterior and interior panelling, flooring, furniture, traditional log buildings, firewood and paper production.

What does a Norwegian spruce look like?

A mature Norway spruce is typically tall and straight, with a narrow, pyramid-shaped crown. When growing in the open, green branches can extend almost all the way to the ground.

Most trees reach between 20 and 30 metres, although Norway spruce trees exceeding 45 metres have been recorded. The bark is generally grey or brown and breaks into thin, papery scales, becoming thicker and more deeply textured as the tree ages.

Its dark green needles are usually between one and 2.5 centimetres long. They grow individually around the twig and are pointed, although generally less painfully sharp than the needles of the introduced Sitka spruce.

The cones provide another useful identification clue. Young female cones are red or green and initially grow upright. Following pollination, they develop into long, brown cones that hang down from the branches. Mature cones can exceed 15 centimetres in length.

Norway spruce should not be confused with a true fir. One easy way to tell them apart is to look at the cones: spruce cones hang down and eventually fall intact, while the cones of fir trees stand upright and gradually disintegrate on the branch.

Where does Norway spruce grow in Norway?

Norway spruce is especially widespread in eastern Norway, Trøndelag and central Norway, and parts of southern Norway. In suitable areas, it forms dense forests and can become the overwhelmingly dominant tree.

Its natural distribution is more limited in western Norway. The high mountains of southern Norway created a major barrier to the tree’s westward spread, although there are some naturally occurring populations, most notably around Voss.

Much of the spruce now seen elsewhere along the west coast was planted as part of large-scale forestry programmes, particularly during the 20th century.

Across Europe, the species grows from Scandinavia and the Baltic region through central European mountain ranges including the Alps, Carpathians and Balkans. To the east, it is replaced by the closely related Siberian spruce.

How old can a Norway spruce become?

Individual Norway spruce trunks can survive for several centuries. However, some mountain spruces have an even more remarkable survival strategy.

Low-growing branches can take root when they come into contact with the ground. New trunks then grow from the same genetic individual, allowing the plant to survive long after an earlier trunk has died.

The best-known example is Old Tjikko in Sweden’s Fulufjället mountains, close to the Norwegian border. Fossil remains associated with the clonal spruce have been dated to approximately 9,500 years ago.

That does not mean its present trunk is 9,500 years old, but that the same genetic individual has repeatedly regenerated on the site since shortly after the last Ice Age.

The Norway spruce as a Christmas tree

With its dark green colour, strong fragrance and naturally conical shape, the Norway spruce is the classic European Christmas tree.

Its main disadvantage is needle retention. Once brought into a warm, dry home, the tree can begin shedding needles relatively quickly. This is one reason many households now choose fir species instead, although the traditional spruce remains popular.

In Norway, spruce branches are also widely used for wreaths, outdoor decorations and greenery around homes and public buildings during the festive season.

Norway’s Christmas tree gift to London

The world’s most famous Norway spruce may be the tree that appears in London’s Trafalgar Square each December.

Oslo has presented London with a Christmas tree . The gift began as a gesture of gratitude for Britain’s support of Norway during the Second World War and has since become a symbol of friendship between the two cities.

The tree must be a naturally growing Norway spruce from the forests surrounding Oslo. Potential candidates are identified years in advance, with the final selection based on appearance, accessibility and whether the tree can survive the long journey to Britain.

Once erected in Trafalgar Square, it is decorated with vertical strings of lights in the Norwegian style. Its sometimes uneven branches regularly prompt jokes and , but that natural appearance is part of the point.

This is not a plantation-grown tree trimmed into a perfect supermarket cone. It is a genuine Norwegian forest tree—and one of the most visible reminders of the Norway spruce’s place in the country’s landscape, economy and traditions.
