"Eurybia sibirica", commonly known as the Siberian aster or arctic aster, is an herbaceous perennial native to north western North America and northern Eurasia, stretching from Scandinavia to Canada. 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 only overlap near the border between the US and Canada, where "E. sibirica" is generally found at higher elevations. The flowers emerge in the summer and display white to pale purple ray florets as well as and yellow disc florets that become purplish as they mature.

Distribution and habitat

"E. sibirica" is present in much of the subarctic region of world, from western North America through Siberia and to Scandinavia. Its range stretches from the northern Rocky Mountains beginning in the south in Idaho and Montana, north to the Canadian provinces of Alberta and British Columbia, farther into the North West Territories and Nunavut, west to Yukon and Alaska, across the Bering Strait into Siberia and continuing west through Russia and into Norway.citation| contribution=Aster sibiricus| title=Flora Europaea| editor-last=Tutin, T.G.; V.

It is also present in wet meadows, in open areas of aspen and spruce woods and along riparian thickets. In addition, it is common growing in sandy or gravelly stream flats, along stream banks and the shores of lakes, on bluffs, in sand dunes and other sandy places, and in both sub-alpine and mountain meadows.Citation
