A daisy, in general, symbolizes innocence and gentleness.
This flower is said to have derived from a Dryad who presided over forests, meadows, and pastures. Roman legend states that the nymph Belides caught the eye of Vertumnus, the god of orchards. This happened when she was dancing with other nymphs at the edge of a forest. Belides didn't want to be the center of attention, so morphed into the flower bellis. This is the daisy's botanical name.
In Victorian times, young, heartbroken women who wished to be loved began a custom using the daisy. A young maiden would pluck a daisy's petals, one by one, and sing, "He loves me, he loves me not," as she pulled each petal, the last petal plucked would be the future of her relationship. This custom is still in use today.
Each flower has a message, according to the Language of Flowers. The daisy brings a message of innocence and purity, saying, "You have as many virtues as this plant has petals," or, "I will consider your request."
A white daisy symbolizes common love.
