Did you know the Sabal Palm is the Florida State Tree? It's not actually a tree though, it belongs to the grass family.
Also called, Cabbage Palm, this tree was vital to the diets of indigenous groups and Florida Crackers. The heart of the tree is used to make Swamp Cabbage. Because this process kills the tree, you and I can no longer harvest the palm hearts of this tree.
You are looking for a mid-sized container among the palm fronds of one Sabal Palm within the park. Please make sure to place back in its space well. We don't want muggles finding it. 
Please be aware that coordinates can be 30ft off. Look for the palms.
