Koreans have loved the rose of Sharon for centuries. As such it was a logical choice for Korea's national flower.

According to records, Koreans have treasured the rose of Sharon as a heavenly flower since ancient times. In fact, the Silla Kingdom called itself Mugunghwa Country. Even the ancient Chinese referred to Korea as "The land of gentlemen where Mugunghwa blooms." Love for the flower was further heightened when Mugunghwa samcheolli hwaryeo gangsan" ("Rose of Sharon, thousand miles of beautiful mountain and river land!") was written into the national anthem of the late 19th century. As the rose of Sharon has been an important part of the Korean culture for centuries, it was only natural that the government adopted it as the national flower after Korea was liberated from Japanese colonial rule.

There are more than 100 cultivars of the rose of Sharon indigenous to Korea. There are single, semi-double, and double types of flowers. Depending on the colors of flower, they are divided into 3 groups, Dansim (flower with red center), Baedal (Pure white flower), and Asadal (pink dots on the edges of the petals). The Dansim, single types of flowers, serves as Korea's national flower.

The rose of Sharon blooms from early July through late October. Some 2,000 to 3,000 bloom on a single plant, which is strong enough to survive even when it is transplanted or cut for decoration or flower arrangements. Thus, the flower represents the wish for lasting national development and prosperity.

Koreans cherish and care for the national flower as it symbolizes the many glories the country has experienced and the trials and tribulations the people have overcome.
