I need a Plant ID Please

I have never seen a flower like this one.
It showed up in one of the flower pots at the greenhouse and I have no idea what it is, it is a trailing plant with rather thick and tender foliage.
Here is the flower.

The flower from the outside.

Part of the plant with buds.

I like it but have no clue what it is.

Thank you, that is just how I feel.

Torenia (Wishbone Flower). Yellow Moon maybe.

You know what? I think you are right I looked on google and the flowers look like the ones on my plant, I guess the seed came with the soil.
I am so tuned to Texas natives that i don't recognize many of the other plants.
Thank you for solving my mystery.

So it's not a native flower?

Not as far as i know, too bad, it is cute.
