Identifying Asters, Chrysanthemums

(Question)

Can asters and mums be distinguished from other plants as they come through the very early stages of growth?
I know these blossom later in the season, and they complement the peonies, Irises and different coloured roses and Phlox. I don’t wish to remove something that looks like a weed by mistake, unlike some advanced gardeners.
In the book Sabbath, author Muller states “Carolus Linnaeus, an eighteenth-century Swedish Botanist, became so enamored with the rthymicity in plants that he grew a garden that could tell time. He planted flowers that opened or closed their blossoms an hours apart, from morning to evening throughtout the day”.
At least I can control some growth by refrigerating some choice items.

Thank you
