Well, it would be really strange. Harry might grow up with a different set of values. Poison Ivy has her own views on nature and power. Harry could end up being more in tune with plants and nature magic. Maybe he'd have a more aggressive approach to protecting Hogwarts, like how Poison Ivy defends her territory in the Batman universe.
If Harry Potter was raised by Poison Ivy in fanfiction, his whole upbringing would be different. He'd probably learn about potions in a more natural, plant - based way. His moral compass might be a bit skewed as Poison Ivy has her own sense of right and wrong. Also, he might have some sort of power related to plants that we don't see in the original Harry Potter series. He could use vines to climb the walls of Hogwarts or even control the Whomping Willow.
In a fanfiction where Harry Potter is raised by Poison Ivy, it would be a complete departure from the original story. Harry would be exposed to a very different environment. Instead of the Dursleys' house, he'd be in a place filled with plants and greenery. He'd learn to communicate with plants, and they might even be his protectors. His relationships at Hogwarts would also be affected. His friends might be a bit wary of his new - found plant - related abilities, and his enemies might be more afraid of him, especially those who are not used to dealing with nature - based magic.
