The Diphylleia grayi or Skeleton Flower, grows in the moist, wooded areas of Japan and China and in the eastern United States. It’s large, fuzzy green, umbrella-shaped leaves are topped with small clusters of beautiful pearly white flowers that bloom from mid-spring to early summer. In late summer, the stalks of flowers are replaced with eye-catching cobalt blue fruit. Oddly, as the petals of the flowers are soaked with water, they lose their white pigmentation and turn into magnificent crystal-clear flowers. Once they dry out, the pale coloring slowly returns and the flowers turn powdery white again.
