You must bring a TRU Shaymin to Floaroma Town in order to get the Gracidea Flower. A TRU Shaymin is the Shaymin you receive at a Toys'R Us Pokemon event. Unfortunately this event has passed, but you can still use someone else's TRU Shaymin to get the flower. You bring the TRU Shaymin to Floaroma and speak to a female NPC roaming around the town. When she see's the Shaymin in your party, she will give you the Gracidea Flower. The flower can be used on any kind of Shaymin.
that kind of flower is not available in diamond cuz Shaymin gets new form only in Platinum
You Can't, You Can Only Get It In Platinum. (And If You Trade It It Goes Away, This Is Because Shaymin's Sky Forme Wasn't Made Until Platinum.)
If you're trading Shaymin from Platinum, don't risk it. You can make it into Sky Forme with the Gradicea flower. But it's your choice if you want to trade or not.
No.you need shaymin in your party if you mean the Gradicea flower
You need to have Shaymin in your party while doing this. It only works if the Shaymin was given in an event or you used Oak's Letter to catch Shaymin in it's natural habitat in Flower Paradise so if you just hack it off using a cheating device, it won't work. As soon as you have Shaymin, go to Floaroma Town and talk to the girl near the sign. She will give you a Gradicea Flower. The flower is used to turn Shaymin into Sky Forme without trading it into Pokemon Platnum when you use it on Shaymin. And since it's a key item, you can turn it back it into Land Forme if you want to.
