I have Google this flower and its really marvelous.

Hi Melis001 Just saw your posting, and wanted to say. I was just in Ft Lauderdale Fl. and saw the Thai spirit. But as I under stand it is the same as Shooting star and also another name which now I forget please look at gingersrus website and you will find this ginger As I understand there is only one variegated hedychium in commerce. I bought mine at home depot in Dothan Al. last year. Last year it was not so great but this year it is looking great and should be blooming in a few weeks.The Thai spirit I saw in south Fl. was over twenty bucks but in a three gallon pot. Wish I knew the name of the nursery, When the guy with the photos sends them maybe he took a photo of nursery name The most beautiful nursery possible on the planet. I though I had died and gone to heaven. James Maloy Hope this helped

posting a follow up from my above follow up. I have been searching Hedychiums over and over and find in my search that the Thai spirit I saw labeled is not the Thai spirit I saw labeled as such So sorry I put all that info. about the wrong plant although I did see Thai spirit it is probably not the one you were looking for. And I personally would like one for my self.
