Revealed: The secret of the poet's daffodil

The secrets of a flower known as the poet's daffodil have fallen to science.

The genetic code of the daffodil's chloroplast - the DNA responsible for photosynthesis - has been mapped for the first time.

Narcissus poeticus was one of the first daffodils to be cultivated, and is linked to the Greek legend of Narcissus.

In Greek mythology, the flower that bears his name sprang up where he died.
