Not a striking difference in color in UV. In visible light the color is even more uniform – creamy white. But not surprisingly, the stigma in the center of the flower has a distinct darker color than that of the petals. The same goes for the anthers, the flat & oblong segments resting between the petals, carrying the pollen. Albeit with a paler blue.
For insects that can see in UV, the most important parts of the reproduction for the plant are those made to stand out from the duller background of the petals.
This flower is past its prime, as the petals are bending downwards and the and anthers are dead.
Native range is Bolivia, Brazil and Paraguay.
