White-backed Hosta

Hosta hypoleuca, the white-backed hosta, is a species of flowering plant in the family Asparagaceae. It is native to eastern Aichi Prefecture, Japan. It is restricted to cliffs, gorges, canyon walls, and other steep, rocky situations, typically near waterfalls or rivulets, and typically south-facing. A protected species, it is considered endangered in Japan due to road construction, and illegal collection for the garden trade.
