orchids

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

'fine flowers' is the definition.
'orchids' can be an answer for 'flowers' (I've seen this before). I am not certain of the 'fine' bit.

'unravelled his cord' is the wordplay.
'unravelled' is an anagram indicator.
'his'+'cord'='hiscord'
'hiscord' anagrammed gives 'ORCHIDS'.

Can you help me to learn more?

(Other definitions for orchids that I've seen before include "Showy plants" , "Flowers from a rich sod" , "Fine tropical flowers" , "Glamorous tropical flowers" , "Chords I turn into flowers" .)
