Yesterday’s flower, tomorrow’s flowers. Now I wish I had blown on its head to scatter it far and yon.

There really is a flower named “Yesterday, today and tomorrow.”  It lives for three days and changes the color of its flower each day, thus the name.  This is not, however, the flower of that plant.
