Weed or plant?

[CharlieandLolaCat]

So I appreciate that a weed is only a plant in the wrong place but after a weed self seeded throughout my flower bed I am a little wary, and completely clueless! Can anyone help me to identify this please?

Thank you

looks like a form of hibiscus, but may be wrong

but its got spurs on the back like aquilegia

Evening primrose (Oenothera)

Yes, Trethew is right. Evening primrose. Nice.

Thank you!

It's amazing, I planted (most) things in my garden and then forget and so it is a constant surprise!
