The national flower of Korea is the mugunghwa (무궁화) , rose of Sharon.
"Tiger has been strongly associated with Korean people and Korean culture
A tiger that has overcome trials and tribulations and understands the world is known to turn white, becoming a white tiger. Although it is a sacred creature that doesn't harm people, it becomes angry when the ruler of the country conducts evil and inhumane deeds. Therefore, it has been told that powerful people become humble and rich people become generous when a white tiger appears." - Wikipedia
