A flower for Rody’s bob

Rody wanted to give his bob flowers for Bob’s Day because he didn’t know what she would want.  (Don’t worry, he’s a much better boyfriend than son!)  I figured it would be better if she could have a flower that lasted forever.  Don’t get me wrong, I love fresh flowers, but every time someone gives them to me I get so sad when they die.  

Does anyone know what this kind of flower is called?  It sure is pretty, whatever its name is.
