I never assumed that the character KOS-MOS' name had any meaning other than 'cosmos' and possibly the Greek origin. But the other week in learning some uncommon kanji that are required for school but easily forgotten, I came across 秋桜 コスモス or kosumosu and in English, Cosmos. It's name includes 'Sakura' but is different from it in that it is actually a chrysanthemum (forgive terrible spelling). The name itself was derived from the Greek origin but like many other words that came in during Meiji from abroad, some Kanji was slapped on.
Damn!
