Obtaining bellossom has not changed in FireRed, you still get them by using a Sun Stone on a Gloom.
Bellossom can be obtained by evolving a gloom with a sunstone.
Evolve an Oddish to Gloom then use a Sun Stone to further evolve it to Bellossom. You must have the National Pokedex upgrade in order to evolve it otherwise nothing will happen.
Bellossom is a Grass type pokemon.
There are two ways to evolve a Gloom, you can either evolve it into Vileplume or you can evolve it into Bellossom. To get Vileplume all you need to do is use a leaf stone on it. Likewise to get Bellossom you have to use a stone on Gloom, but this time it is a Sun Stone.
Catch a Gloom, then give it a Sunstone.
Use a sun stone on a Gloom.
In all of the Pokemon games Oddish evolves to Gloom when it is level 21, then you can evolve it into Bellossom with the sun stone or Vileplume with the leaf stone.
You cannot find a bellossom but you have to evolve it from a gllom with some sorta stone. once you get a gloom then you evolve it with a sun stone to get bellossom or if you want a vilploom (spelling?) then evolve one with a leaf stone. Catcatcat87:)
