The tree is a Quercus virginiana, or Southern Live Oak, which is the official state tree of Georgia.
The name 'Treaty Oak' was coined in the 1930s by a local journalist to create a myth that peace treaties between settlers and Native Americans were signed under its branches, though no historical record of such events exists.
The tree survived the Great Fire of 1901 and various hurricanes due to its resilient, deep root structure.
The park was named after Jessie Ball duPont, a philanthropist who purchased the property in 1964 to ensure the tree's preservation.
In 2004, the tree underwent extensive restorative care, including the installation of a lightning protection system and specialized irrigation to support its aging root system.
Treaty Oak is the centerpiece of Jessie Ball duPont Park, featuring a Southern Live Oak estimated to be over 250 years old. The tree possesses a canopy span of approximately 145 feet and stands about 70 feet tall. It is officially protected by the City of Jacksonville after a successful community campaign in the 1960s to prevent its removal for development. The park grounds provide a quiet, shaded urban retreat on the Southbank of the St. Johns River. Interpretive signage near the base details the tree's history and the efforts taken to preserve its root system and structural integrity.

Bring bug spray, as the dense shade and proximity to the river can attract mosquitoes.
The park is compact, so combine your visit with a walk along the nearby Southbank Riverwalk.
Do not climb on the low-hanging limbs, as the tree is fragile and requires careful preservation.
Stay on marked paths to avoid soil compaction around the critical root zone of the tree.
