Two toned tulips

The boy bought me a large bunch of pink and yellow tulips for my birthday. I quickly took a few snaps today as I am sure they will start to droop in a couple of days.

It made be wonder what variety the two toned tulips were. So I googled it and then I sat back and thought,

'oh my god I am getting old, I am researching flower types!'

but then after unsuccessfully finding a match at my first search result I gave up, which made me think

'Yay I am not that old afterall, I still have a life'.

If any one knows though, please tell, I promise not to call you old!
