In selecting a national tree, Americans had some fabulous species to choose from. The United States is home to both the biggest living things (California’s redwoods) and some of the oldest known living things (Nevada’s bristlecone pine). The majestic white pine played a prominent role in early American history. The most popular state tree is the sugar maple, with its showy fall foliage.
But the winner was an even better choice. Oaks can live for many years and attain great sizes. As they age, gnarled branches curve and twist, forming beautiful patterns. Their stately forms have long made oaks symbols of patience and majesty. Even the leaves and acorns are popular symbols.
Better still, oaks grow across the United States, from East to West coasts. States that call oaks their official tree include Maryland, Georgia and Iowa.
