It's alright, Vileplume is one of less than 20 Kanto mons that still haven't gotten special privileges (crossgen evolution, Mega, Z-Move, Gigantamax, Regional, Convergent, etc.) and is eligible to do so.
Depending on whether or not Gen 10's gimmick features new forms, it's practically guaranteed to be among those who flourish!
