March: This month is synonymous with the onset of spring (in the Northern Hemisphere). Accordingly, the flower associated with this month is Daffodil also known as Jonquil or Narcissus. The colors of the bloom include white, yellow and orange. A gift of these flowers conveys the hidden meaning of friendship and happiness.

Daffodils bring cheer to the spring garden with abundant flowers in hues of yellow, white, pink, and salmon. Varieties are available in a range of sizes and forms. Flowers may be single or double, grow singly on a stem or with multiple flowers per stem, and height varies from 6 to 20 inches. Daffodils grow best in areas with cold winters, cool springs, and cool summers. Choose varieties that mature at different times to extend the bloom season. Unlike many spring-flowering bulbs, daffodil bulbs are not eaten by mice or voles.
