Vileplume is not found in the wild in Pokemon R/S, you must evolve it from a Gloom by Leaf Stone.
you have to use a leaf stone on gloom or you can get a bellosom with a sunstone used on gloom.
Vileplume does not evolve.
It can evolve Nuzleaf into Shiftry and Gloom into Vileplume. There could be more though.
Use a leaf stone on your Gloom. Ta-da! You now have Vileplume! OR use a Sun-Stone on it. Ta-da! BELLOSSOM!!!! To evolve it into a Vileplume, use a Leaf Stone. To evolve it into a Bellossom, use a Sun Stone.
