US Symbols Online: State Trees

Each of the 50 states have designated an official "State Tree." All of the state trees, except the Hawaii's state tree, are native to the state in which they are designated.  Some of the Latin names you see here may be different from those you may have seen before due to changes in plant nomenclature; we have chosen to list the current valid botanical name. Where more than one accepted common name exists, the common name in the legislation has been listed. Include year of designation.

Many of the Official State Tree Designations of the 50 States listed here can be found in the U.S. National Arboretum's "National Grove of State Trees." However, because the climate in Washington doesn't allow the growth of all of the state trees, trees have been substituted  for some of the states.

1. California has designated two distinct species as its state tree.
2. Although Iowa did not designate a specific species of oak as its state tree, many people recognize bur oak, Quercus macrocarpa, as the state tree since it is the most widespread species in the state.
3. Although no specific species of magnolia was designated as the state tree of Mississippi, most references recognize the Southern Magnolia, Magnolia grandiflora, as the state tree.
