Ultraviolet photograph of the flowers of a Crocosmia (Montbretia) cultivar. In UV light the throat of the flower appears much darker than it does under visible light. Some insects, such as many bees, can see ultraviolet light, and it is thought that these UV markings help guide them to where the nectar is located.
Crocosmia is a popular garden plant, with over 400 cultivars produced. The flowers are bright red or orange and arranged suboppositely on a long spike.
