Hibiscus syriacus, the common garden Hibiscus, also confusingly called Rose of Sharon in some areas (a name originally applied to other plants), is a flowering shrub in the plant family Malvaceae native to much of Asia. It is vase-shaped, reaching 2-4 m in height. It is also known as "Rose of Althea" and is widely planted in areas with hot summers for its very attractive white, pink, red, lavender, or purple edible flowers.

Hibiscus syriacus 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 [1]. The flower's name in Korean is mugunghwa (Hangul: 무궁화).
