The flower looks like evening primrose to me, Oenothera biennis, but the leaves don't look quite right. The flower also looks a bit like Californian poppy, but again, leaves not quite right...
I wondered if it could be a yellow horned poppy not totally sure regarding the leaves. Also wondered about Oenothera but there are so many I am unable to help.
