You might be right about the top flower being a marigold, although the marigolds I've seen the most are elliptical-shaped, not so rounded like a ball. And these are a bit larger than the marigolds I usually see. There are so many varieties of these flowers, I get confused easily! THANK YOU!
You are welcome! It is true! There so many varieties of the marigold, but, I am for sure that it is not a mum. They have giant marigolds also, but look it up for your own curiosity.
