Plant HELP please....

CLICK ON PICTURE TO MAKE IT BIGGER!!!
I picked these up today at a local place that sells plants and all proceeds go to the Cancer Society.
These were $1.oo a piece so I bought three. The problem is it says Angelonia on the container but when I looked it up online, it's not the same plant. I just love how this looks and for a buck, I don't care of it doesn't come back. But I would be thrilled if it did!
Can anyone that gardens help me out and give me a name of this plant?
