The Heavenly Capital City of Flowers ~ Bridge of the Lotus (Demetori/ZUN)
As a side note, this song is listed as "天空の花の都 ~ Bridge of The Lotus" which would fully translate as "The Capital City of Flowers in the Sky", some translate it as "The Heavenly Capital of Flowers", the translation above keeps the meaning but adds a bit of flair, but it doesn't distort the meaning enough for it to be considered "wrong". Anyway, this unnecessarily long text is to inform you that you can take any word from these translations, those are a lot of words to choose from 'cuz you guys are cool.
