Shrubs deciduous, erect, 2-4 m tall. Branchlets stellate puberulent when young. Stipules filiform, ca. 12 mm, stellate pilose; petiole 3-6 cm, stellate puberulent; leaf blade cuneate, ovate, or orbicular, usually 3-lobed, 7-12 × 7-12 cm, papery, basal veins 3-5, both surfaces sparsely stellate puberulent, lobes usually triangular, central lobe larger, base cuneate, broadly cuneate, or nearly rounded, margin acutely serrate. Flowers solitary, axillary on upper branches. Pedicel 1-2.5 cm, densely yellow stellate puberulent. Epicalyx lobes 6 or 7, lanceolate-oblong, free, connate at base only, 17-25 × 3-5 mm, densely stellate puberulent, apex obtuse or acute. Calyx campanulate, longer or shorter than epicalyx, lobes 5, ovate-triangular, densely golden stellate puberulent. Corolla purplish, 7-9 cm in diam.; petals obovate, 6-7 cm, stellate villous abaxially. Staminal column 4-5 cm. Style branches 5, glabrous. Fruit unknown. Fl. Jun-Jul.
Scrub in valleys; 500-1000 m. Guangxi, Guizhou, Hunan (Hengshan, Qianyang), Jiangxi (Lushan).
Hibiscus sinosyriacus is very similar to H. syriacus. The main differences are the broader epicalyx lobes (3-5 mm, not 0.5-2 mm, wide), larger petals (6-7 cm, not 3.5-4.5 cm), and wider leaves (7-12 cm, not 2-4 cm, wide). It is also similar to H. labordei but differs from that species in having the leaf base cuneate to nearly rounded, not rounded to slightly cordate, and the style branches glabrous, not hirsute.

产江西庐山、湖南衡山和黔阳、贵州松桃和平坝及广西桐岭。生于海拔1000米的山谷灌丛中。本种枝多叶茂,花大型,极有观赏价值,应广为引种栽培。
本种极似木槿,主要区别在于小苞片特宽,叶较大,基部宽楔形,边缘具尖锐粗齿而相异;与贵州芙蓉不同处在于贵州芙蓉叶基部圆形、截形至微心形,和花柱枝被毛而不同。
