The Skeleton Flower

Skeleton flowers – turn transparent with few drops of water

The Skeleton Flower

The Diphylleia grayi is an extraordinary flower with white petals that turn beautifully transparent upon contact with water. During light rain showers, the delicate blooms transform into blossoms as clear as glass, fitting its common moniker “skeleton flower.”

The plant can be found growing on moist, wooded mountainsides in the colder regions of Japan and China come late spring. The Diphylleia grayi is recognizable by its large, distinctly umbrella-like leaves topped with small clusters of pearly white blossoms that undergo a magical transformation in the rain.
