Oreocereus celsianus I think.

With a fake flower (the colour even isn't right). You can remove the fakery (it will leave a small wound which will heal over if you keep it dry) with some needlenosed pliers. Did you know you were getting an unreal plant?

Hi,
I didn't know about the fake flower, so I am disappointed about that. But I got a great price on it and would have even bought it knowing the flower is fake. Thanks for letting me know what it is.
I think they should have to put some kind of notice on the plant that it is not all real. I'm sorta curious if it will fake out some bees as I have it outside now. I was looking at the flower and thinking it still had a little way to go before opening all the way.

The plant is real, the flower is not. ;)

I thinks it is an old man cactus, but not too old.
