Cloudberries are an arctic berry similar to raspberries and other bramble but closely related to the rose family which inludes strawberries and cherries as well as raspberries. Cloud Berry grows in the coldest regions along the arctic circle - Scandanavia and Russia as well as parts of Alaska and Canada.
They are tart and juicy and not commonly cultivated, although they can be, they generally grow wild. The berries are similar in appearance to Raspberries but are a tad smaller and salmon colored. They are also called yellowberry, knotberry, baked apple berry, averin berry by the Scots, Norwegian Berry in Norway and Salmon Berries  in other places.
Cloud Berries are not self pollinating, at least 2 plants are required to produce fruit. There are male and female plants, so one of each gender is required.
