'low-blooming' originates from modern English, specifically the compound of 'low' and 'bloom', where 'low' meant 'not high' (from older Germanic roots) and 'bloom' meant 'flower' (from Old English 'blōma').

'low' traces to older Germanic/Old Norse and Old English forms (e.g. Old Norse 'lágr') and 'bloom' developed from Old English 'blōma' to Middle English 'blome' and then modern English 'bloom'; 'low-blooming' is a contemporary compound formed from these elements in modern English.

Initially the components meant 'not high' and 'flower'; over time the compound came to be used to describe plants whose flowers occur low on the plant or that have sparse/insignificant flowering.
