Can you name the species?
Pilosella (formerly Hieracium) aurantiaca, I believe.
Agreed, though I would have liked to see the foliage, as cichorioid daisies are not easy to identify.
I wouldn't be sure it is "wild".
Finnish flora is a mix of several things. After the Ice Age there was a tundra phase, and some plants still reflect it, especially in the outer archipelago. Then there was steppe, and finally taiga, which is still evolving. For example, spruce is still gaining ground from birch. Add human influence, e.g. dirt used for ballast in sail ships, and horticulture. Manor houses used to compete with their gardens.
As an Alpine flower, P. aurantiaca could be either a remnant from the early tundra phase (TvÃ¤rminne is close to the archipelago), or a later garden plant (TvÃ¤rminne is an old homestead, and has a history of botanical research).
I don't know anything about flowers, but that immediately reminded me of this photo I took a couple years ago in Canada, just north of Lake Huron: http://imgur.com/ivVQW.jpg
