Indoor flower similar to daisy?
 

I have three daisy flowers that I keep inside of my apartment. They
get sunlight as well. Each initially had 2 or 3 bright flowers. They
have since gone away. However, the plant part is doing fine and has
grown on each. It's been since before the summer and the flower part
has never come back. Should I be doing something for the flower to
come back or is that seasonal?

Also, is there another plant I can keep indoors similar to a daisy or
sunflower?

Thanks,
Brett
