Summary edit

Description
English: Epilobium palustre (Marsh willowherb) photographed in visible light (left), ultraviolet light (middle), and infrared light (right).

In visible light the flowers appear pale pink with darker pink veins. The pollen in the centre of the flowers is pale yellow.

In ultraviolet light the vein patterns on the petals appear lighter than the petals. The centre of the flower exhibits a dark nectar guide.

In infrared the flowers have a similar tonality to their appearance in visible light. The veining on the petals is still visible, but not quite as pronouced. The seed pod, stalk and leaves appear much brighter.
