State Tree and Flower Chart | State Trees | State Tree Facts and Trivia. Each of the 50 states and several United States territories have designated an official tree and flower. Many of the state flowers are actually trees as well -- some states have chosen the same species as state tree and as state flower. All of the state trees, except the Hawaii state tree, are native to the state in which they are designated. Many of the state flowers are from other parts of the world and were chosen because of their beauty or importance, not because they represent the natural flora of the state they represent. Some states have designated a state wildflower, as a symbolic native species.
