It basically only evolves gloom into bellossom. You can obtain gloom by evolving an oddish at level 21, althought you can also catch it at other areas but it is quite rare to find (check your pokedex to know where). It can also evolve sunkern into sunflora, but you can only find those in pokemon emerald in the safari zone.

Evolve it using an Thunder Stone.
The Pokemon that evolve using a thunderstone are: Pikachu into Raichu Eevee to get a Jolteon
Evee can evolve by using a water stone to evolve into vaporeon, using a thunderstone makes it a jolteon, using a fire stone makes it a flareon. Now you can get espeon and umbreon in the game but its completely random. Just have the evee love you and level it up and it will evolve to espeon or umbreon and like i said its random. If you want espeon and umbreon the easiest way is to get them from ruby or sapphire or emerald or even Pokemon colosseum or even Pokemon xd gale of darkness.In Pokémon FireRed, Eevee can evolve at any level because Eevee can evolve into only 1 of 3 Pokémon in Pokémon FireRed. Eevee can evolve into a Vaporeon if you use a Water Stone on it, if you use a Thunderstone on it then it'll evolve into a Jolteon and if you use a Fire Stone on it then it'll evolve into a Flareon.
