The Diphylleia Grayi is a wonderfully unique flower whose petals turn clear as glass when it’s splattered with raindrops. Commonly referred to as the skeleton flower, it hails from the moist wooded mountainsides in the colder regions of China and Japan. The flowers come out in late spring, with large, fuzzy green, umbrella-like foliage topped with small clusters of pretty white petals. And when it rains, they’re such a wonderful sight to behold.
