Despite the specific epithet, Hibiscus syriacus originated in China but was taken into cultivation very early and was distributed to the Middle East along early trade routes. It is a very popular frost-hardy flowering shrub from which many named cultivars have been developed, some of which have been given formal scientific names. These include:

H. syriacus var. alboplenus Loudon (白花重瓣木槿 bai hua chong ban mu jin): Flowers double, white, 6-10 cm in diam.

H. syriacus var. amplissimus L. F. Gagnepain (粉紫重瓣木槿 fen zi chong ban mu jin): Flowers double, pink-purple with red center.

H. syriacus var. brevibracteatus S. Y. Hu (短苞木槿 duan bao mu jin): Leaf blade rhomboid, base cuneate. Flowers single, purplish. Epicalyx lobes very small, 3-5 × 0.5-1 mm, silky.

H. syriacus var. elegantissimus L. F. Gagnepain (雅致木槿 ya zhi mu jin): Flowers double, pink, 6-7 cm in diam.

H. syriacus var. grandiflorus Rehder (大花木槿 da hua mu jin): Flowers single, peach or red.

H. syriacus var. longibracteatus S. Y. Hu (长苞木槿 chang bao mu jin): Flowers single, purplish. Epicalyx lobes nearly as long as sepals, 15-20 × 1-2 mm.

H. syriacus var. paeoniiflorus L. F. Gagnepain (牡丹木槿 mu dan mu jin): Flowers double, pink or purplish, 7-9 cm in diam.

H. syriacus var. totoalbus T. Moore (白花牡丹木槿 bai hua dan ban mu jin): Flowers single, white.
