Hibiscus syriacus is a hardy deciduous shrub. It is upright and vase shaped, reaching in height, bearing large trumpet shaped flowers with prominent yellow tipped white stamens. The flowers are often pink in color, but can also be dark pink (almost purple), light pink or white. Individual flowers are short lived, lasting only a day. However, numerous buds produced on the shrub's new growth provide prolific flowering over a long summer blooming period. The soil in which the Hibiscus thrives on is moist but well drained, and organically rich. Hibiscus syriacus is highly tolerant of air pollution, heat, humidity, poor soil and drought.

The branches are thin and gray, white lenticeled, with raised leaf scars and small buds. Stems and branches do not branch very much unless pruned, resulting in many long, straight stems that originate from about above the ground, giving rise to the shrub's overall vase shape. The leaves appear unusually late in the season, in May. in solid colors of white, red, purple, mauve, violet, or blue, or bicolors with a different colored throat, depending upon the cultivar. Extending from the base of these five petals is the pistil at the center, with the stamen around it. These basic characteristics give the H. syriacus flower and its many variants their distinctive form. The plant can bloom continuously from July through September,

Hibiscus syriacus is fairly easily propagated from either seeds, with variable results, or by layering or cuttings, cloning the original.

Old shrubs can develop trunk cankers that may eventually prove fatal to the plant. The plant has some susceptibility to leaf spots, blights, rusts and canker. Japanese beetles, whiteflies and aphids are occasional insect visitors. Japanese beetles can severely damage foliage if left unchecked.

Hibiscus syriacus, also known as the Korean rose, is the national flower of South Korea. The flower appears in national emblems, and Korea is compared poetically to the flower in the South Korean national anthem. The flower's name in Korean is mugunghwa (hangul=무궁화) or mokkeunhwa (hangul=목근화). The flower's symbolic significance stems from the Korean word mugung, which means "eternity" or "inexhaustible abundance". Various state emblems of South Korea contain Hibiscus syriacus; it is generally considered by South Koreans to be a traditional symbol of the Korean people and culture.

Hibiscus syriacus was originally endemic to Korea. It is recorded that it was brought to Japan in the 8th century and cultivated for horticulture. According to records, it was prolific on the Korean Peninsula before the 1st century. By the end of the 17th century, some knew it to be hardy: Gibson, describing Lord Arlington's London house noted six large earthen pots coddling the "tree hollyhock", as he called it, "that grows well enough in the ground". By the 18th century the shrub was common in English gardens and in the North American colonies, known as Althea frutex and "Syrian ketmia".
