Yes, it's a native plant, but what does that matter? Probably Oenothera biennis, aka 'Evening Primrose'.

If you allow them to self seed around the garden they will become a weed. Take the seed that you want then remove the stems quickly.

I don't know the correct name but I think we call it Evening Primrose. If it sets seed there is no reason why you shouldnt be able to grow some.
