'seasonal-blossoming' originates from the combination of 'seasonal' and 'blossoming', where 'seasonal' refers to a specific time of year and 'blossoming' refers to the act of flowering.

'seasonal' and 'blossoming' have been used in English since the Middle Ages, with 'seasonal' deriving from the Latin 'sationem' meaning 'a sowing' and 'blossoming' from the Old English 'blostmian'.

Initially, 'seasonal' meant 'pertaining to a season' and 'blossoming' meant 'to produce flowers', and this meaning has largely remained the same in modern usage.
