Not a tulip?!

Evening all,
I wonder if anyone can tell me what this is?
I bought 2 packs of mixed tulip bulbs and planted them earlier this year. I have been rewarded with a lovely mix of tulips including some gorgeous almost black ones. Anyway one of the bulbs grew and grew to at least twice the height of the tulips and then flowered earlier this week. I have no idea what it is but I am intrigued.
