Name a plant that wasn’t at some point “invasive”. You can’t. We call plants invasive when we see their spread, and native otherwise. But whether a human observed a particular organism spreading matters precisely not at all.
Native plants is a term used to describe plants that were present before humans got involved.
It's a human centric way to view the world but I guess it's better than us trying to dick around making everything human agnostic considering we're all human and share a bunch of human context with each other.
