Marsha claims that the bees frequented the daises the most because they are atracted to the color of the flower

Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower's scent can have particular appeal to bees, and its bright colors may lure the bees in.

Explanation:

Bees have good color vision to help them find flowers and the nectar and pollen they offer. Flower colors that particularly attract bees are blue, purple, violet, white, and yellow.
