The corollas get their blue color from anthocyanidin and the very sensitive cyanidin. The latter dye is actually red, but appears blue here due to an iron-magnesium-calcium complex. The petals fluoresce under ultraviolet radiation and are thus conspicuous from a distance. The marginal tubular flowers are enlarged as show flowers, they are brilliant deep blue and sterile.
Nigella damascena, also known as Love-in-a-mist and Devil in the bush, is an annual garden flowering plant, which belongs to the buttercup family Ranunculaceae. Native to southern Europe, north Africa and south-west Asia, it is found on neglected, damp patches of land. Its common name “Love-in-a-mist” comes from the flowers being nestled in a ring of multifid, lacy bracts. The flowers, blooming in early summer, are most commonly different shades of blue, but can be white, pink or pale purple, with 5 to 25 petals.
