Identification: Need Houseplant Identification

Can anyone identify this houseplant?



A former employee left it in our office. It's very hardy and about 21 inches high. It has beautiful flowers but it doesn't bloom very often (less than once a year), and they don't last very long.

No one in the office knows what it is. Maybe someone here does.

 

It's a Clivia, probably Clivia miniata.

I agree with Clivia. I think the common name is Kaffir lily.

 

Thanks! That's it!

After a quick search on Google, I have abundant information. Thanks for the clue on what to look for.
