Else it is wild AFAIK. Blueberry as we know it is not very easily cultivated.
Yes, or to put it even more exact... (sorry for the long post)
The thing you (probably, especially if you are from the US) mean by blueberry is indeed
pensasmustikka:
http://en.wikipedia.org/wiki/Blueberry
It's bigger, and is green inside. It doesn't grow here wild, only cultivated, and I would guess most sold here has been imported.
The thing we natives (probably) mean by blueberry is bilberry:
http://en.wikipedia.org/wiki/Bilberry
It's smaller, and is dark blue inside. It's not cultivated (it's very hard to cultivate), all sold ones have been picked from the forest, although they may be imported.
The big "
mustikka" sold in shops in small punnets are blueberries, or
pensasmustikka, even though the sign may only say "
mustikka". I very much doubt any of them have been grown wild. The ones sold by the litre/kg (usually from stalls) is wild bilberries, or
mustikka, and like I said, always picked from the forests. The frozen
mustikka you buy in shops is bilberries, although the frozen "
luomu mustikka" you saw I guess could have been blueberry/
pensasmustikka, as the "luomu" part makes otherwise no sense. Luomu doesn't mean though that it has been grown wild, just that it has been grown in a way that adheres to the "luomu" principle.
That said, native Finns refer to both blueberries and bilberries as
mustikka and few realize that they aren't the same thing... but, most will know what you mean if you say "pensasmustikka". Almost nobody has heard of the word "bilberry", as the word we learn in school for our
mustikka is blueberry. I had absolutely no idea until somebody pointed it out here on Finland Forum.
