This fabulous selection of the Japanese species, H. hypoleuca, is spectacular with its large leaves, dusty grey-green on top and chalky white underneath. This species (rare in the wild), is native to sunny rock cliffs, where it establishes itself in the tiny crevices. In the wild, plants often produce only one leaf. In cultivation, it will develop into a 2' wide clump. The white leaf back serves as protection against the hot reflected sun. In early summer, the clump is topped with 2' arching scapes of light lavender flowers.
