'carnation-fragranced' is a modern English compound formed from the noun 'carnation' and the participial adjective 'fragranced' (from 'fragrance'/'fragrant'). 'carnation' entered English from Late Latin 'carnationem' via Old French, and 'fragranced' is a Modern English adjectival/past-participial formation from 'fragrant'.

'carnation' changed from Late Latin 'carnationem' (from 'carnatio' meaning 'flesh-color' related to 'caro'/'carn-') through Old French into Middle/Modern English as 'carnation'. 'fragrant' comes from Latin 'fragrans' (present participle meaning 'smelling') via Old French into Middle English; the noun 'fragrance' and the adjectival/past-participle form 'fragranced' are later Modern English developments. The compound 'carnation-fragranced' is a recent English formation combining these elements.

Initially, 'carnation' primarily referred to a flesh-color (from Latin) and later came to denote the flower now called a 'carnation'; 'fragrant' originally meant 'smelling' and has kept that general sense. The compound 'carnation-fragranced' specifically denotes 'having the scent of carnations', a specialized descriptive use formed in modern English.
