'floral-scented' originates from Modern English, formed as a compound of 'floral' and 'scented', where 'floral' relates to 'flower' and 'scented' means 'having a scent'.

'floral' comes from Latin 'floralis' (from 'flos, floris' meaning 'flower'), while 'scented' derives from Old French/Latin roots related to 'sentire' ('to perceive, smell'); the compound 'floral-scented' is a relatively recent descriptive formation in modern English.

Initially the elements meant 'relating to flowers' ('floral') and 'having a smell' ('scented'); combined, they came to mean specifically 'having the scent of flowers' without major semantic shift.
