Usually fire bush requires dry ground.
The give-away, if you look in the photos lower right, is that the plant is growing on the berm of an elevated road that traverses across one of the swamp’s deepest spots.
As for the original question,
The native slash pine sort of fits the bill:
Its bark is naturally fire proof.

It has to wait out the invasion of shallow water
and find a way somehow to survive.
