Omalotheca norvegica, synonym Gnaphalium norvegicum, is a European species of plants in the family Asteraceae.[1] It is known as the highland cudweed[2] or Norwegian arctic cudweed.[3] It is native to eastern Canada and Greenland, and widespread across much of Eurasia from the Mediterranean north to Finland and Iceland and east to Siberia.[1][4][5]

Omalotheca norvegica is similar to Omalotheca sylvatica, heath cudweed. However, it is 8 to 30 cm tall, the leaves are 3 veined, and all roughly equal in length. The leaves are also wooly/hairy on both sides.

In Great Britain, it is a rare plant found in central Scotland and in the northern highlands, found on acidic mountain rocks. It flowers July to August.[6]
