I'm not sure exactly what you mean to ask, but I'll take a stab at it . . .
Most Bulbos smell like various sorts of yuck, as they're pollinated by flies. I'm not sure about the scent of either of the parents of this hybrid, but chances are better than not that at least one of them smells bad.
There are a number which have no discernable scent, and a couple that smell good. B. macranthum smells of cucumber and cloves, B. ambrosia smells of honey, and B. sulawesii smells nicely of black pepper (or, at least, mine does).
