Asterales
True, or English, daisy (Bellis perennis).
Paleobotanists estimate that the first members of the Asteraceae family may have evolved approximately 50 million years ago. This estimation is based on the discovery of well-preserved fossils found in Argentina that date back to the Eocene Epoch, which spanned from 56 million to 33.9 million years ago.1
