The official state flower and state tree of Missouri can be confusing. Our state flower blooms on a tree and our state tree has flowers!
On March 16, 1923, Governor Arthur M. Hyde signed a bill naming the white hawthorn blossom, (Crataegus,) the official state floral emblem of Missouri. Though a specific variety of hawthorn is not named in the legislation, the Missouri Department of Conservation asserts that the downy hawthorn, (Crataegus mollis,) is the species deserving of the recognition.
In 1955 the state legislature designated the Flowering Dogwood as the State Tree of Missouri.
