Riddle Me This #1 Answered

This is a riddle from Artemis, so I'm going to go ahead and post the answer right now. I'm just trying to get all the literature off of Artemis and onto Of The Thing Sung, so I won't be posting anything new for a couple of days while that process happen.
Deal with it :)
Oh, and Merry Christmas!

Remember this?

I am as bright as the sun
With a center that is black
I can make you smile
But a mouth I lack
Who am I?

Drum roll please
*Drums roll on desk

 

It's a sunflower!
