'multiflorum' originates from Latin, specifically the adjective 'multiflorus', where 'multi-' meant 'many' and 'flos, floris' meant 'flower'.

'multiflorus' in Classical Latin produced the neuter form 'multiflorum', which was adopted into Neo-Latin/botanical Latin and used as a species epithet in scientific names.

Initially it meant 'many-flowered' in Latin; over time it has retained this meaning and is used in botanical contexts to denote plants with many flowers.
