This is in a class of its own - the only species in this genus - although it is closely related to Rodgersia, and used to be included in that genus. It comes from moist woodland areas in East Asia. A moist woodland garden habitat or beside a shady stream or pond would suit it fine. It has large (to 90 cm) lobed leaves and in summer produces hundreds of tiny, creamy flowers in panicles that can reach 1.5 m.
