Trade for it from Diamond, Pearl, or Platinum, Eevee only evolves into Leafeon when it levels at Moss Rock, in Sinnoh, same goes for Galceon at Ice Rock.
You have to trade from Diamond, pearl or platinum

That's not true. you have to
Touch the moss rock in eterna forest then Level up near the Moss Rock (Why not Leaf Stone is beyond me)
No, as Moss Rock (Eterna Forest) or Pinwheel Forest are impossible to get to. If you want to evolve your Eevee into Leafeon you must trade it to Diamond, Pearl or Platinum, level it up at Eterna Forest, and then trade the Leafeon back to SoulSilver.
Yes u can
you cant get glaceon or lefeon in soulsilver
I'm pretty sure you need to find a Leaf Stone.
Eevee can't evolve into leafeon in soulsilver you have to trade it to diamond and pearl and evolve it there. The ilex forest doesn't have a Mossy Rock - which is what evolves eevee into leafeon.
You need to trade with pearl and diamond for leafeon and glaceon. The 5 other forms are all attainable within soulsilver.
Eevee ----ANSWER 2: it wont work, for Leafeon, u need to have a person with diamond, trade an eevee over there, have them go to the forest after "flower town" and have eevee go up a level, it should evolve into Leafeon after that
You have to use a leaf stone on your eevee. Sorry, I don't know where to find a leaf stone though. : ) hope this helped!
whoever has a leafeon i will trade a flareon
Leafeon is a Grass type pokemon.
You can catch Leafeon in Celadon City where Misty is.
You can't,but you could send it over to a Diamond or Pearl game and level it up in Eterna forest. :D I hope this helped!
If you get it 8 haircuts/massages and then level it up, it should evolve. Galceon, Leafeon, Megezone, and Probepass must be traded for.
