Reportedly wed good, mature woman (8)
I believe the answer is:
marigold
'woman' is the definition.
'reportedly wed good mature' is the wordplay.
'reportedly' shows a homophone (sound like).
'wed' becomes 'marry' (synonyms).
'good' becomes 'g' (abbreviation).
'mature' becomes 'old' (associated in meaning).
'marry' sounds like 'mari'.
'mari'+'g'+'old'='MARIGOLD'
(Other definitions for marigold that I've seen before include "The flower has a gold rim, oddly" , "Garden plant of the daisy family" , "Flower - grim load (anag)" , "Bright orange-yellow garden flower" , "Yellow or orange flower" .)
