I am still trying to figure out what this flower is. Can you get a clearer picture of the bloom and the leaf and the seed pods? When you say it came from the Netherlands, do you mean it is native to the Netherlands? What is the condition of the soil wet or dry? I will continue to work on the identification, so that I can give you the right care instructions. Do you see any new growth forming?

the leaves are thinner and smaller, the blades around the leaves are much smaller too (in fact, they are tiny and neat not with some big blades but small same size blades for every leaves. its a kind of a dental like leaves). yes, and the lines on the leaves are much neater with only a few curved lines curved outward toward the tiny blades. the petals on the flowers are not oval, but more circular and bigger. when the flowers bloom, there are more pollen than Anemone piperi plant and there are bigger pods for seeds to grow inside too.
p.s. the leaves are smoother than the Anemone piperi plant… please send me information about this plant, thank you.
