It's a Bromeliad. They sometimes die after flowering but usually they produce baby plants which you can grow on. Beware, you could be overwhelmed with them, like my sister did a few years ago. Google bromeliads and you can see what care they need.

It usually takes about two years for the babies of that type of bromeliad (Guzmania hybrid) to bloom. Larger kinds may take three.
If you get a good clump of babies going in a broad, shallow pot, you might get flowers every year, as they get out of synch.
