Rubus arcticus, the Arctic raspberry, (includes Rubus arcticus ssp. acaulis - (Michx.)) is a species of slow-growing bramble belonging to the rose family. Its dark red fruit is considered a delicacy. In the Pacific Northwest it is sometimes called the nagoon or nagoonberry, a name which derives from the Tlingit neigóon. A measure of the quality of its fruit is expressed in its Russian name княженика knyazhenika, signifying the "berry of princes". It grows in northern Sweden, Norway, Finland, Russia (Siberia), in few locations in Estonia, Lithuania and in parts of North America. The fruits of the Arctic raspberry are very tasty and, among other uses, make jam and liqueur, or flavour tea.
