'florogenesis' originates from Neo-Latin and Greek elements: 'flora' (from Latin 'flos, floris', meaning 'flower') and Greek 'genesis' ('γένεσις', meaning 'origin' or 'creation').

'florogenesis' was formed in modern botanical (Neo-Latin) usage by combining Latin-derived 'flora' and Greek 'genesis'; it entered English scientific usage in the 19th–20th century as a technical term for flower formation.

Initially it carried the sense 'origin or beginning of flowers', but over time it has come to denote the process or developmental stages of flower formation ('the development of flowers').
