Crocosmia sp. (Montbretia) flowers Vis UV IR comparison

Crocosmia sp. (Montbretia) flowers Vis UV IR comparison
A comparison of how Montbretia flowers appear in visible light (top), ultraviolet light (middle), and infrared light (bottom).

In visible light the flowers appear red with a yellow throat.

In ultraviolet the throat of the flower is much darker. These UV markings are often referred to as 'Nectar guides', as they can be seen by bees and other insects, and help them find the flower's nectar.

In Infrared light the foliage in the background, the stem of the flower spike, and the seed pods on the spike all appear much brighter (than in visible light), having roughly the same reflectance as the flowers.
