You can obtain the gracidea flower in one condition. You have to transfer the Shaymin from the Nintendo Event or from Oak's Letter via Mystery Gift in Pokemon Platinum.
So first have the Shaymin in either Platinum, HG or SS and transfer it to your White game.
PS. You needed 2 DS to transfer.
if you have shaymin she will give to but if she doesent then beat her up :)
Have you Pokemon fans been wondering how to get a gracidea flower on Pokemon black & white? Well i know how! First you must have a shaymin that CAN turn into sky-form. Next go into the Pokemon center at Lacunosa Town. If you see to the left, there is a girl next to a shelf of books. She has lots of gracidea flowers. You must have your shaymin that can turn into sky-form to get it but in your party Pokemon. Next talk to her. She will talk about your shaymin. Then she will hand you the gracidea flower. Then you have it the shaymin can't be hacked or it won't work. (Any regular shaymin that was not received by cheats should be able to turn into sky-form)
You cannot catch a Shaymin in Pokemon White. However, if you migrate a Shaymin from a Gen IV game, you can get the Gracidea flower to make it sky forme. Go to Lacunosa City (east of Opelucid City after you beat the game) and there will be a girl in the Pokemon center who talks about the Gracidea flower. Talk to her with Shaymin as the first Pokemon in your party and she will give you the Gracidea. (it may not work if you have a hacked, non-event shaymin.
first you need to go back to Shaymin village and talk to the Shaymin closes the the dungeon entrence on the right.
no you can't you have to use mystery gift and download the Oak's Letter and bring it to the white rock on route 224
No, items can't be migrated, but if you migrate Shaymin across, take it to Lacunosa Town's Pokemon centre, a woman inside will give you the Gracidea.
no items can't be tranfered
I don't think you can get an axe in Pokemon Black/White. :(
Vullaby is not featured in Pokemon White, only Pokemon Black. The only way to obtain it in White is to trade it from Pokemon Black.
You cannot obtain Thunderus in white by catching it. You must trade it in from Pokemon Black.
Yes, you can change Shaymin while it is in Land Forme over to its Sky Forme in Pokémon White however you will need the Gracidea in order for it to change it forms. You can get the Gracidea from a character in the Lacunosa Town Pokémon Center.
You wait for the event.
