Prunus spinosa (Blackthorn; Sloe) flower photographed in visible light (left), ultraviolet (middle), and infrared (right).

In visible light the flower has white petals with a green centre. The stamens have white filaments with brown anthers. The pistil is green. The leaves are a dark green and the branch is a mid-tone brown.

In ultraviolet the flower appears darker, while the branch appears lighter (in comparison to the rest of the plant).

In infrared the plant's leaves appear much brighter. There is little difference in tone between the flower's petals, the sexual parts of the flower, the leaves, and the branch - they all appear quite bright.
