'flowering' is the definition.
(thesaurus)

'woman investing a shilling in modern' is the wordplay.
'woman investing' becomes 'flo' (I can't justify this - if you can you should give a lot more credence to this answer).
'a shilling' becomes 's' (abbreviation e.g. Lsd - pounds, shillings, pence).
'in' means one lot of letters goes inside another.
'modern' becomes 'recent' (I've seen this before).
's' put inside 'recent' is 'rescent'.
'flo'+'rescent'='FLORESCENT'
