The crowberry (Empetrum nigrum) is part of the undergrowth of the sandy esker of Kallahdeniemi. Its berries resemble bilberries and are edible. The flavour is mild.
A subspecies found in northern Finland, the mountain crowberry produces more and larger berries than the crowberries found in the south. The berries are rich in both vitamins and fibre. They also contain more flavonoids than any other berries growing in Finland. The berries are used to make violet thread dye.
