Daisies symbolize innocence and purity, and can also be used to signify new beginnings. The flower meaning of daisy is "I will never tell," so it can be representative of loyalty as well. Because of its symbolism, it may be a nice gesture to buy daisies for a friend that recently moved away for a job or another reason, to show him or her the friendship is lasting.
Daisies are remarkably durable and are known to spread easily, so in a garden setting it's important to keep them contained. During the night, daisies retract their petals and then open up again at dawn. The leaves of these flowering buds are edible and can be used in salads or as greenery to make homemade meals look professional. There are many varieties including the Spanish daisy, blue daisy, lazy daisy and African daisy.
