A scented flower forest, one in Georgia (8)
I believe the answer is:
gardenia
'a scented flower' is the definition.
'forest one in georgia' is the wordplay.
'forest' becomes 'arden' (I've seen this before).
'one' becomes 'i' (Roman numeral).
'in' is an insertion indicator.
'georgia' becomes 'ga'.
'arden'+'i'='ardeni'
'ardeni' put inside 'ga' is 'GARDENIA'.
(Other definitions for gardenia that I've seen before include "Shrub such as the Cape jasmine" , "A reading (anag.)" , "Drainage for shrub with white or yellow flowers" , "bloomer!" , "Bad drainage can produce a fragrant flower" .)
