Daffodils belong to the genus Narcissus, and Narcissus is their botanical name that comes from the Greek word narke ("numb"). The flower is named after Narcissus in Greek legend.

Some people call daffodils "jonquils" (from the Spanish name for this flower) or "lent lilies" (because they start blooming as the season of Lent begins).

Daffodils originate from Mediterranean region, and were first cultivated by Romans.

The International Daffodil Register records 26,000 species and cultivars of this plant in shades of yellow, white, orange and peachy pink.

The daffodil is the emblem of Wales and is worn on St David's Day.

Daffodils release sap which is toxic to other flowers, and they should be left in water on their own for at least 12 hours before mixing with other flowers.

In the language of flowers, daffodils signify chivalry and respect.
