You're all assuming that the primal plants are ancestors of the player's house plants, which I don't think at all. I think they're simply other plants in the same family as the player's house plants, that eventually became extinct over time, like the dinosaurs (I don't believe in macroevolution, but that's a convoluted argument that I don't want to get into). This would explain why they're more powerful than their modern counterparts.
