Flowers in February

This year's winter is a dreadful mistake. I took the photos below on the 17th and 18th of February, in my garden.

I have learned, that these flowers that appeared out of nowhere (my neighbour must have planted them in his garden and they sowed) is Winter Aconite (Eranthis hyemalis) and their appearance in February is not that surprising as I had originally thought. Aconite is the first early-spring flower in Poland and it already blooms between February and March.
