Pancratium maritimum, or sea daffodil, is a species of bulbous plant native to the Mediterranean region and south-western Europe. That plant can also be seen on the south Bulgarian and north Turkish coasts of Black Sea, where it is threatened with extinction. It grows on coastal sands or just above the high tide mark. Other vernacular names are Sand Daffodil, Sand Lily and the Lily of St. Nicholas. The Latin maritimum means "of the seashore".
