Bellis perennis "Pomponette"

My mom always referred to these as "little buttons". They are adorable :)

Warning: Science Ahead

These are actually related to the common daisy, Bellis perennis, though I am unsure of the exact relationship between them. If the two plants are able to produce viable seeds, they may be considered variants of the same species. I find this incredible, since they look so different! I wonder if the divergence occurred naturally or resulted from cultivation...
