Unknown Forest Plant Identification

[Alex6015]

Hi all. About a week ago I took a reddish long stemmed plant from a forest around here and I planted it in my garden.It had no flowers. Just some leaves on its stem. I watered it and in a few weeks it made some yellowish-green flowers with a pleasant scent of honey and lemon (I think ) and I want to know what it is. Here are some pics with it after it flowered.Please tell me what it is called.

Your plant looks a bit like missouri sundrops, a lovely native
Oenothera missouriensis or O. macrocarpa ( Missouri Primrose Sundrops ), but the flowers of that are usually a bit more cupped than yours look like. Here's a link to some sundrops pictures, see what you think

Thanks rainbow but...the flowers are different. Theyre not simple flowers (like pansies and others), the flowers are in pairs and the both come from the same leaf-like circle. And as I said, it smells like honey and lemon BUT I did not buy it from somewhere, I just took it from a forest where it grew in the wilderness so it can be a variation to some species.However the main thing is how the flowers are arranged(as you can see in the pictures,in pairs). Thanks . If anyone knows what are these don't't hesitate to reply.

Oh and...wasn't Missouri (Missouri Sundrops) a state in the US? I live in north-eastern Romania, in Europe. I doubt I will fiind American species there.

It could be some kind of Bupleurum, perhaps Bupleurum longifolium.

This is just a wild guess on my part, but could it be a yellow form of Jeffersonia dubia? All I can find are pictures of the plant with light lavender flowers, so I may be totally off base with my guess. Jeffersonia dubia is a common forest plant in your area, though.

those florets have the quintessential look of euphorbia, of which there are many varieties.

I think that genus is also native to america, although I could be wrong.
