"A dwarf birch for the larger rock garden with small rounded deep green leaves. " from Edrom Nurseries.

"The dwarf birch is common all over Iceland except for some regions of the interior. It is a creeping dwarf-shrub (woody stems) which can be easily recognized from it's big brother the downy birch, (B. pubescens) by the shape of the leaves. The leaves of the dwarf birch has a more round shaped leaves with the broadest size towards the end of the leaf, where the downy birch has a more diamond shaped leaf. " from Flora of Iceland.

" Betula nana is a dicot belonging to the Betulaceae family of plants. It is a perennial dwarf shrub and is common in tundra climates. It can be seen in 14 states of North America , Northern Scandinavia and parts of Scotland and Siberia .

Betula nana can grow up to 1 metre in height and has stems which extend along the ground. It is a wind pollinated, monoecious plant which favours wet but well drained sites. It grows on nutrient poor, acidic soils which can be xeric and rocky. B. nana has a low tolerance of shade." from Aberystwyth Universty.

"Numerous wildlife species eat dwarf birch. Moose and caribou browse dwarf birch in Alaska. In south-central Alaska, dwarf birch comprises 13% of vegetation and accounts for 9% of the moose diet. Dwarf birch buds, leaves, and sprouts are preferred food items for caribou in Alaska in the spring and early summer. Leaves are available until mid-September but are less palatable than willow (Salix spp.) leaves by then.

Ptarmigan eat the buds, catkins and twigs of dwarf birch in Alaska. Dwarf birch and bog birch buds and catkins comprised 11% of the food in rock ptarmigan crops in Alaska in spring, 12% in summer, 45% in fall, and 79% in winter. For willow ptarmigan the 2 birches comprised 0% of food in crops in spring, 3% in summer, 4% in fall, and 12% in winter. Spruce grouse eat dwarf birch seeds in central Alaska.

Dwarf birch foliage provides forage for a number of herbivorous insects. In Alaska, the total number of herbivorous insects decreases with increases in latitude and altitude and distance from the white spruce forest zone." from U.S. Department of Agriculture.
