Yoruichi found it appropriate that he smelled like camellias.
He smelled like the very flower his squad symbolized, but with a different tang, bitter and almost dark, truer to an orchid rather than a camellia. The orchid was strong, beautiful and exotic. The camellia was soft, delicate and proper. Once a year since her death, it was the camellia Byakuya placed upon Hisana's grave.
To Yoruichi, he gave a single orchid.
OoOo
Bah, this isn't exactly how I wanted this, I know it doesn't directly relate to "smell" but it just wrote itself this way. Thanks again for the reviews, guys.
Also, a multi-chaptered ByaYoru fic is in the works, so keep a lookout for the first chapter!
