A nameless, passionate person with a bouquet (8)
I believe the answer is:
aromatic
'with a bouquet' is the definition.
(a bouquet is a pleasant smell)
I can't explain the remainder of the clue.
(Other definitions for aromatic that I've seen before include "giving out bouquet" , "Fragrant or spicy, smells nice" , "Coat I arm to be smelly" , "Sweet-scented" , "Spicy material" .)
