This flower obtained its first name from Japanese scholars during the Japanese rule over Korea. Its name was changed several times from time to time and only recently settled for ‘Bok-ju-meo-ni-ran. This was once known to inhabit the most part of Korean Peninsula except the Jeju island. However, it’s now hard to find in the wild nature, thereby leading to the designation as Endangered Wild Species Class II of Korea by the Ministry of Environment.
