I try my luck with this Chrysanthemum species which suprisingly is still blossoming this late on our terrace.
The plant belongs to the same family (Asteraceae) as the sunflower does. Asteraceae are renowned for their symmetrical pattern of individual florets which are arranged in interconnecting spirals, where the number of left spirals and the number of right spirals are successive Fibonacci numbers (source)!

The pics were taken today in the afternoon sun with an Iphone15.
