"Skeleton Flowers" Become Transparent When It Rains
There is nothing more attractive in nature than a beautiful flower. Some are bright as can be, some come with amazing smells and color combinations, and some just do things completely different – just like the unique skeleton flower.
The fading of the color in the petals when wet happens because of a loose cell structure present in the white flowers and not due to the pigment being washed out. When it rains, water fills in the cells of the petals, thus turning it clear, same as water. It is unclear, though, whether this trait gives advantage or disadvantage to these small flowers.
