This is Titan arum, also known as the corpse flower. It flowers rarely, but when it does the overpowering smell of rotting meat fills the area due to it being a carrion plant. The stench attracts flies and beetles for pollination. The flower(s) itself is enormous, having the largest inflorescence in the world. It cannot technically be the largest flower however, because it is actually composed of many smaller flowers.
