description_en: Genus of 8 or 9 species of perennials, sometimes grown as biennials, from woodland and stony sites in China. They are cultivated for their large, foxglove-like flowers, which are 2-lipped and borne in terminal racemes. The leaves, arranged in basal rosettes, are large, obovate to oblong, shallowly lobed or toothed, conspicuously veined, and hairy. Grow at the front of a sunny border; in regions with mild, damp winters grow permanently, or over-winter, in a cool greenhouse.
hardiness_en: Fully hardy to frost hardy.

comment:
comment_ja: 最近の分析ではハマウツボ科の最基部に位置するが、今後、別の科の姉妹群となる可能性もあるので、 YlistのようにRehmanniaceae ジオウ科としておくのが妥当かもしれない。かつてはイワタバコ科やゴマノハグサ科に分類されることもあった。
