Posted by The Bernese Oberland is known not only for its mountains and lakes, but also for its remarkably diverse plant life.
Due to large differences in altitude, climate and soil conditions, the vegetation changes significantly from the valley floors to the high alpine zones.
Each altitude level has its own characteristic plant species, many of which are perfectly adapted to the Alpine environment.
Below is an overview of typical plants found at different elevations and in special habitats of the Bernese Oberland.
1. Valley floors and low elevations (up to approx. 800 m)
In the lower parts of the Bernese Oberland – including valleys, lake shores and gentle foothills – the climate is relatively mild.
Fertile soils and sufficient rainfall support a rich and varied vegetation.
Beech (Fagus sylvatica):
One of the dominant deciduous trees in low-altitude forests.
Together with fir and spruce, beech forms extensive mixed forests that are typical for this zone.
Field maple (Acer campestre):
A widespread tree species found along forest edges, hedgerows and open woodland areas in the lowlands.
Burnet (Sanguisorba):
A characteristic plant of moist meadows and riverbanks, often growing near streams and wetlands.

2. Mid-altitudes (approx. 800 m – 1,500 m)
At medium elevations, the landscape is shaped by mountain forests, alpine pastures and open meadows.
This zone represents the transition between valley vegetation and true alpine flora.
Spruce (Picea abies):
The most common tree species in this altitude range.
Spruce forests dominate large areas and are often mixed with silver fir and beech.
Bearberry (Arctostaphylos uva-ursi):
A low-growing shrub found on mountain slopes and dry meadows.
It is well adapted to poor soils and harsh conditions.
Alpine kidney vetch (Anthyllis vulneraria alpestris):
This plant thrives on nutrient-poor grasslands and plays an important role in alpine meadow ecosystems.
3. Alpine zone (approx. 1,500 m – 2,500 m)
Above the tree line, the environment becomes increasingly harsh.
Cold temperatures, strong winds and thin soils limit plant growth.
Nevertheless, many specialized species flourish in alpine meadows, rocky slopes and scree fields.
Alpine rose (Rhododendron ferrugineum):
A well-known alpine shrub that prefers acidic soils.
In early summer, its bright red flowers cover large areas of mountain slopes.
Edelweiss (Leontopodium alpinum):
Perhaps the most famous alpine flower.
Edelweiss grows on dry, calcareous and stony soils and is strictly protected in Switzerland.
Gentian (Gentiana acaulis):
Known for its intense blue flowers, gentian thrives on alpine grasslands and limestone soils.
It is one of the most striking plants of the high Alps.
4. Subalpine and high-alpine vegetation (above approx. 2,500 m)
At very high elevations, vegetation becomes sparse.
Only a small number of highly specialized plants are able to survive in the cold, windy and rocky environment near glaciers.
Glacier buttercup (Ranunculus glacialis):
One of the highest-growing flowering plants in the Alps, often found close to melting glaciers.
Alpine sea holly (Eryngium alpinum):
Also known as blue thistle, this plant grows in scree fields and dry alpine meadows.
Sharp stonecrop (Sedum acre):
A hardy succulent species that stores water in its leaves and thrives on dry, rocky soils.
5. Moors and wetland habitats
Wetlands, bogs and moorlands occur at various elevations in the Bernese Oberland.
Their plant life is strongly influenced by water saturation and nutrient-poor soils.
Sphagnum mosses:
Key plants of raised bogs, capable of storing large amounts of water and contributing to peat formation.
Cotton grass (Eriophorum):
Easily recognizable by its white, fluffy seed heads, cotton grass is typical of alpine and subalpine bogs.
Bog bean (Menyanthes trifoliata):
A wetland plant found in marshes and at the edges of mountain lakes.
The flora described here represents only a small selection of the plant diversity found in the Bernese Oberland.
Thousands of plant species occur in the region, shaped by altitude, climate and soil conditions.
