''Bergenia'' 〔''Sunset Western Garden Book,'' 1995:606–607〕 (elephant-eared saxifrage, elephant's ears) is a genus of ten species of flowering plants in the family Saxifragaceae, native to central Asia, from Afghanistan to China and the Himalayan region. ==Description== They are clump-forming, rhizomatous, evergreen perennials with a spirally arranged rosette of leaves 6–35 cm long and 4–15 cm broad, and pink flowers produced in a cyme. The leaves are large, leathery, ovate or cordate, and often have wavy or saw-toothed edges. For most of the year, the leaves have a glossy green colour, but in cooler climates, they turn red or bronze in the fall. The flowers grow on a stem similar in colour to a rhubarb stalk and most varieties have cone-shaped flowers in varying shades of pink. These can range from almost white to ruby red and purple. The common names for ''Bergenia'' are pigsqueak (due to the sound produced when two leaves are rubbed together), elephant's ears (due to the shape of the leaves) and large rockfoil. ''Bergenia'' is closely related to ''Mukdenia'', ''Oresitrophe Astilboides'' and ''Rodgersia''. The creator of the taxonomic genus name, Conrad Moench, honoured the German botanist and physician Karl August von Bergen by coining the name ''Bergenia'' in 1794. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bergenia」の詳細全文を読む スポンサード リンク
