The fast-growing tulip tree is perfect for parks and streets due to its resistance to cold and insects. Originally from North America, the tulip tree also represents the fact that Korea and the US signed the Korea-US Treaty in Incheon.
Beloved by the people of Incheon for many years for its beauty, roses can be found all across Incheon. As a symbol of activeness and passion, roses represent the active and passionate nature of Incheoners.
Given that Incheon is a seasonal home for the migratory red-crowned crane, several districts across Incheon have names inspired by cranes - Songhak-dong, Cheonghak-dong, Seonhak-dong, and Hakik-dong (*"Hak" means crane in Korean). In particular, Munhak-dong was the former administrative capital of Incheon.
Since Incheon is a harbor city, blue represents the color of the sea, a strong spirit, and the aspirations to sail the vast open seas.
