Vegetative characteristics
The alpine bearberry is a deciduous dwarf shrub with creeping branches up to 50 centimeters long. However, it only reaches heights of up to 10 centimeters with short ascending end shoots. The simple leaves are up to 5 centimeters long, obovate, finely serrated, ciliate long towards the base and have a somewhat wrinkled top with impressed veins .
Flowers and leaves appear simultaneously in May or June. In autumn, the leaves turn very noticeably bright purple.
Generative characteristics
The inflorescence contains only two to five flowers. The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The pink to greenish-white corolla is about 5 millimeters long, spherical-jug-shaped, with a small opening and ends in five outwardly curved corolla lobes.
The initially red, then ripe black stone fruits have a diameter of about 9 millimeters.
The basic chromosome number is x = 13.
Occurrence

It is found in temperate Asia from Siberia over the Altai to Mongolia ; in Europe it occurs far in the north and in the mountains with a southern border in Italy , the Balkans and Spain ; from Greenland to the arctic north to the US states of Maine and New Hampshire , this species occurs in North America. In Japan, Arctostaphylos alpina var. Japonica Hultén occurs.
The alpine bearberry is not common and grows on fine soil and moderately acidic moist humus in shady, long snow-covered dwarf shrub heaths and pine bushes in subalpine to subalpine altitudes . In the Allgäu Alps, it rises from 820 meters west of the Bruck power station in Bavaria to over 2000 meters. In Central Europe it is a character species of the Arctostaphylo alpinae-Loiseleurietum, but also occurs in the Erico-Rhododendretum hirsuti.
