Morphology

four-o'clock + family

Although 'family' transparently signals a group, the first element 'four‑o'clock' is a lexicalized common name for a plant and is not interpretable as 'a group of flowering plants' from its literal parts ('four' + 'o'clock'). The botanical sense requires specific lexical/taxonomic knowledge rather than composition from the constituents, so a B1 learner who only knows the constituent words would not reliably derive the MWE meaning.

Etymology

Four-o'clock family comes from a garden plant called four-o'clock whose flowers open in the late afternoon around four o'clock. So the family name was used for a group of related flowering plants, which is why it refers to many plants that open their flowers in the afternoon.
