説明（英語）: Genus of 2 or 3 species of rhizomatous perennials from grassy meadows, scrub, and woodland in China and Japan. They are cultivated for their foliage and graceful inflorescences. Erect, glaucous stems bear alternate, heart-shaped, palmately lobed, glaucous, grey-green to olive-green leaves, to 25cm (10in) long, with rounded, toothed lobes and prominent veins. Numerous petalless, tubular flowers, to 1cm (1/2in) long, with 2 or 4 sepals and a cluster of stamens, are borne in airy, plume-like panicles. The stems and leaf-stalks produce a yellowish orange latex. Grow in a mixed or herbaceous border or as free-standing specimens; they may also be grown among shrubs or used to form a tall screen. They can be invasive.
