Purple color defines royalty, power, and luxury. Although in some cultures it is also a symbol of grief. The Daisy here seems to be lamenting as it sheds one petal at a time moving towards its withering phase.
We must acknowledge every emotion. Although, when you experience pain and sorrow, remember that “This too shall pass”, that grief is only temporary.
Interesting Fact: Just like humans, daisies love to catch some sleep at night. Sure they may not be technically sleeping, but they do close their petals over their eyes until the sun rises back up in the morning.
