Two weeks ago I picked a flower from my backyard near my compost in Östergötland, Sweden and pressed it. Now, I realise that I don't actually know what kind of flower this is. I tried using Pl@ntNet identify and it gave me some promising suggestions, namely crocus nudiflorus and crocus speciosus.
However, the former blooms in autumn and this one was picked — and clearly blooming — in spring. Additionally, one source (unfortunately not in English), claims that it does not reproduce in Sweden, so it seems strange to me that it would appear in my backyard then given that it was not planted there (but I could be wrong about this being relevant, please correct me if that's the case).
The latter flowers in October, so it doesn't seem likely to be the right one either. It also doesn't look quite right to me.
While trying to find good sources for my claims I stumbled upon crocus vernus which seems to fit the bill given that it reproduces in Sweden and blooms in spring, but I'm not sure how to verify this.
What kind of flower could the one in the picture below be?
