Eurybia sibirica, commonly known as the
Siberian aster or
arctic aster, is an herbaceous perennial native to north western North America and northern Eurasia. It is found largely in open areas of subarctic boreal forests, though it is also found in a wide variety of habitats in the region. It is similar in appearance to
Eurybia merita, but their ranges overlap only near the border between the US and Canada, where
E. sibirica is generally found...
