The state or quality of efflorescence; the process or condition of blooming, flowering, or reaching peak development.
From 'effloresce' plus '-ency' suffix, which creates abstract nouns describing states or qualities. Less common than 'efflorescence' but more archaic in tone.
This triple-suffix word (ex + florescence + ency) is a linguistic mouthful, which is probably why it lost out to the simpler 'efflorescence'—but it appeared frequently in Victorian scientific writing.
