State Symbols of Hawaii
Hawaii has adopted a variety of state symbols; this article highlights just a few of them.
Flag of the State of Hawaii
The flag was first adopted by the Kingdom of Hawaii in the early 19th century and continued to be used even after the kingdom’s dissolution in 1893. Hawaii is the only U.S. state whose flag includes the symbol of another country. The Union Jack in the upper-left corner reflects Hawaii’s historic ties with Britain. The eight stripes represent Hawaii’s eight main islands, and the colors do not hold any specific symbolic meaning.
Seal of the State of Hawaii
The design of the state seal was adopted in 1959, when Hawaii became the 50th state of the United States. It is based on the original seal of the Republic of Hawaii, created by Honolulu resident Viggo Jacobsen. The design draws from the royal coat of arms of the Hawaiian Kingdom, which was used during the reign of King Kamehameha III.
State Bird
Hawaii’s official state bird is the endangered Hawaiian goose (Branta sandvicensis), locally known as the nēnē due to the sound it makes. It can be found on four of Hawaii’s islands, typically inhabiting lava plains, pastures, and shrublands.
State Fish
Hawaiian law also recognizes an official state fish—the reef triggerfish (Rhinecanthus rectangulus). Notably, the fish emits grunting sounds when stressed, likely to warn other fish of potential danger.
State Flower
Hawaii’s state flower is the yellow hibiscus (Hibiscus brackenridgei), which commonly grows on the islands of Hawaii, Molokai, Lanai, and Maui at elevations of 394 ft–2,592 ft.
State Mammal
Among the state symbols is the endangered Hawaiian monk seal (Neomonachus schauinslandi), which primarily inhabits the northwestern region of the Hawaiian Islands.
State Plant
The official state plant is taro (Colocasia esculenta), known in Hawaiian as kalo. In traditional Hawaiian cuisine, it serves a role similar to that of potatoes, and even its leaves are used in cooking.
State Tree
Hawaii’s state tree is the kukui tree (Aleurites moluccanus), which was historically used to provide light. The nuts of the tree were strung on palm fronds and burned sequentially.
State Dance
The hula is a legally recognized symbol of Hawaii. This traditional dance form tells stories and is usually accompanied by chanting or singing. Its style varies across the different islands.
State Musical Instrument
The ukulele is officially recognized by local legislation as a state symbol. This musical instrument was brought to Hawaii by Portuguese immigrants from Madeira and the Azores in the late 19th century.
