In Japan, they found the first flower that changes color many times.

The chameleon flower is the Japanese Causonis (Causonis japonica). Usually plants can change shade as they grow. Often a new color signals to insects that it is ready to pollinate. Causonis was the first flower described that could repeatedly change color and return to the old one. The scientists called this ability bidirectional color change. It turned out that the color change is associated with the peculiarities of the reproductive system. What is the evolutionary benefit, scientists do not yet know. In the male stage, causonis is orange. When the stamen ages and falls off, the flower turns pink. After a few hours, the pistil grows and the causonis turns orange again.
