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.
Gloom doesn't evolve into Bellossom by leveling up. Use a Leaf Stone and TADA! A Bellossom! : )
Gloom will evolve to Bellossom, and Sunkern will evolve into Sunflora using a Sun Stone.
