The bright yellow blooms of daffodils are a wonderful sign that spring has arrived. The daffodil is virtually synonymous with spring. Though their botanic name is narcissus, daffodils are sometimes called jonquils, and in England, because of their long association with Lent, they're known as the "Lent Lily." Lore connecting the daffodil to not only a sign of winter's end but a lucky emblem of future prosperity is found throughout the world. In Wales, it's said if you spot the first daffodil of the season, your next 12 months will be filled with wealth, and Chinese legend has it that if a daffodil bulb is forced to bloom during the New Year, it will bring good luck to your home.
