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]
