Having a bouquet prepared for our side only at first (11)

I believe the answer is:

odoriferous

I'm a little stuck... Click here to teach me more about this clue!

'having a bouquet' is the definition.
I can't judge whether this defines the answer.

'prepared for our side only at first' is the wordplay.
'prepared' indicates anagramming the letters.
'at first' indicates taking the first letters.
The first letter of 'only' is 'o'.
'for'+'our'+'side'+'o'='foroursideo'
'foroursideo' anagrammed gives 'ODORIFEROUS'.

Can you help me to learn more?

(Other definitions for odoriferous that I've seen before include "Giving off a smell" , "Smelly" , "Fragrant" .)

I've seen this clue in The Times.
