shaymin sky forme help

how do get shaymin to turn into his other forme?? i tried talking tothat girl in floarama town and she just tells me about the special flower, how do i get her to give it to me?

You need the TRU shaymin and not just an ordinary shaymin to get the flower.

EDIT: it's from an event.

ok, i hate it, im pretty sure the one i got in a trade is dodgy, oh well

If you want one, i can give mine to you if you like.

i dont really have anything that great to trade for it

I already have the flower so you can just give me some random pokemon.
