Cultural Significance

In Korea, Hibiscus syriacus is the national flower (Mugunghwa), symbolizing the Korean spirit of perseverance and resilience. The name "Mugunghwa" means "eternal flower," representing the enduring nature of the Korean people. In Victorian flower language, it represented "consumed by love." Despite the species name "syriacus," it is not from Syria but was named based on early botanical misidentification. The shrub blooms prolifically during late summer when few other shrubs flower, earning it the biblical name "Rose of Sharon."
