Gen 2 is finally here and with it come not just new Pokémon like Bellossom and Sunflora, but new items like the Sun Stone, too.
That, in turn, means new methods for evolution: the Sun Stone was used for evolving Bellossom and Sunflora in the main Pokémon games by simply 'using' the evolution stones on them - a mechanic that's not been featured in Pokémon Go before now.
So with that in mind, how do you evolve Gloom into Bellossom, and evolve Sunkern into Sunflora, and likewise how do you get the Sun Stone in Pokémon Go?.
The answers to all that can be found below, but while you're here, it's worth noting that there are several other new, special items which work in precisely the same way: the Metal Coat for Steelix and Scizor, the Dragon Scale for Kingdra, the King's Rock for Slowking and Politoed, and the Up-Grade for Porygon2.
How to evolve Gloom into Bellossom in Pokémon Go
Over in the main series of Pokémon games, Gloom evolves into Bellossom - as opposed to Vileplume - in a kind of branching evolution chain. To get Vileplume, you'd need to use a Grass Stone on Gloom, whilst to get Bellossom you'd need to use a Sun Stone.
Evolution stones themselves haven't been in the game until the current update - in fact the originals, like the Grass Stone, still aren't in the game - and so the mechanic itself is new, too.
To evolve Gloom into Bellossom, then, you'll need to get yourself a Sun Stone, along with the required amount of Candy, and simply head to the normal section of the menu where you'd go for evolving the Pokémon and carry on with the usual steps from there.
- Gloom to Bellossom Evolution cost - 1 Sun Stone and 100 Oddish Candy.
How to evolve Sunkern into Sunflora in Pokémon Go
This one was originally up for contention, as it wasn't clear whether Sunflora would follow the Raichu-style method of evolving, where evolution stones from the original games were replaced with Candy in Pokémon Go, or the Bellossom method which uses the evolution stone, as above.
It turns out you do indeed need the Sun Stone to evolve Sunkern into Sunflora, and that can be done in the usual way from the game's menus.
- Sunkern to Sunflora Evolution cost - 1 Sun Stone and 50 Sunkern Candy.

How to get the Sun Stone in Pokémon Go
Regardless of Sunflora's evolutionary method, you'll be needing the Sun Stone for Bellossom. To get it, you'll simply need to get spinning those Pokéstop wheels, because so far that's the only way of acquring one for now.
Fortunately, there is some strategy here after all! A special evolution item is far more likely to drop on the seventh day of your PokéStop Daily Bonus streak. There's no guaranteeing which evolution item you'll get, but with only five in the game at least you hopefully shouldn't have to wait too long to get a hold of all the items you need.
