What tree symbolizes Florida as its state tree?

The tree that symbolizes Florida as its state tree is actually the palm tree, which is widely recognized for its association with the state's tropical climate and landscapes. Palm trees are iconic in Florida and are often depicted in tourism materials and associated with the state's identity.

The other trees listed, such as Bur Oak, Red Maple, and Willow, do not represent Florida's unique natural environment in the way the palm tree does. Florida's state tree captures the essence of its warm climate and is a prominent feature in many of its natural habitats, making it a fitting symbol for the state. The Bur Oak, while significant in other regions, is not native to Florida, thus making it an incorrect choice for this question.
