List of Washington state symbols
While some of the symbols are unique to Washington, others are used by multiple states. For example, the willow goldfinch (also known as the American goldfinch), Washington's state bird, is also an official symbol for Iowa and New Jersey. Washington's state grass, bluebunch wheatgrass, is also a symbol for the state of Montana. The square dance and apple are commonly used state dances and state foods, respectively. While most states have an official motto and nickname, Washington's motto ("Al-ki", meaning "by and by" in Chinook Jargon) and nickname ("The Evergreen State") have never been officially adopted by the Legislature.
