This depends on the location of the flower and the conditions in which it exists. You could get really creative with a flower planted and growing outside...worms, butterflies, sun, rain, wind, the neighborhood cat, mice, snails, caterpillars...etc.
Inside flowers would experience conversation, music, air conditioning, perhaps not close enough to a light source, household pets, children playing frisbee or football indoors, so many things to consider.
This can be a fun exercise! Have a blast with it! :)
