Windbreak planting can be important to improve the climate of a garden in an exposed area.

Windbreak planting can be important to improve the climate of a garden in an exposed area. The effect is increased by adding a small hill, thus creating new garden spaces and keeping disturbing elements out of sight. This is what we have intended here. Even if this collection is not prepared for visitors, a number of genera well suited for northern climates are shown, e.g.: lilacs (Syringa), elders (Sambucus), honeysuckles (Lonicera), spiraeas (Spiraea) and larches (Larix).
On the hills there are also groves of two species not often planted here – the American sweet birch (Betula lenta) and the common sea-buckthorn (Hippophae rhamnoides). The latter has its northern world limit as a native species within the municipality of Tromsø.
More than 30 shrub-forming rowan (Sorbus) species are found both here and scattered throughout the garden. They are beautiful both when flowering in spring and when white or pink berries contrast the reddish foliage in the autumn.
