'flower-phobic' originates from English, specifically the element 'flower' combined with the Greek-derived suffix '-phobic', where 'flower' meant 'blossom' and '-phobic' meant 'fear'.

'flower' changed from Old French 'flor' (from Latin 'flōs, flōris') into Middle English forms like 'flour'/'flower' and eventually became the modern English 'flower'; the element '-phobic' is from Greek 'phobos' (meaning 'fear') via Late Latin/medical New Latin '-phobia' and entered English as the combining form '-phobic'.

Initially, 'flower' meant 'blossom' and the Greek root 'phobos' meant 'fear'; combined in modern usage they form the adjective meaning 'having a fear of flowers'.
