FOX is reportedly recasting the role of the plant-obsessed Ivy Pepper on "Gotham." The character is set to transition into the villainous Poison Ivy for the third season, and become a series regular.

Child actress Clare Foley portrayed Pepper in the first two seasons of the show, but but will be replaced by an actress in their late teens, as the character evolves into the eco-terrorist we all know and love.
