Comparison of the flower of Campanula persicifolia 'Telham Beauty' photographed in visible light (left), ultraviolet light (middle), and infrared light (right).
In visible light the flower appears a light violet colour with a white three lobed stigma in the centre.
In ultraviolet light the flower still appears pale, but the stigma is much darker.
In infrared light the flower's tonality is similar to that in visible light. The stalk and leaf appears brighter.
