I think this is a zinnia. I’m not sure. I know it isn’t a mum. There is a church about half a block away that has these flowers lining their walk. The long stretch of flowers is multi-colored — reds, oranges and yellows, but the short stretch is this patch of solid, light green flowers. While I prefer the multi-colored patch, I find this color unusual and stop to look at them most mornings when I’m walking the dogs. If you know for sure what they are, please let me know.
