The flowering plant growing from Abigail's foot signifies that she is beginning to transform into a female version of Swamp Thing. This is caused by a combination of Dr. Arcane's genetic experiments on her and Swamp Thing using his regenerative powers to heal her. It suggests she will become a swamp creature like Alec Holland.

Foreshadowing: Swamp Thing's healing powers and Arcane's genetic manipulations both contribute to this transformation.

Swamp Thing was originally scientist Alec Holland, who was transformed into a bog creature during a confrontation with Dr. Arcane and his henchmen a few years before this movie. Arcane's experiments with swamp animal genes, combined with the circumstances of Holland's apparent death and resurrection in the swamp, resulted in his transformation into the plant-based superhero.

Foreshadowing: The movie establishes that Swamp Thing has a pre-existing history with Dr. Arcane from the first film.
