Morphology

Oenothera + biennis

The binomial is directly compositional: 'Oenothera' names the genus (night-opening/ evening-primrose herbs) and 'biennis' is the Latinized adjective meaning 'biennial', so the phrase denotes the biennial species of that genus. This follows predictable botanical naming conventions rather than idiomatic meaning, making the overall sense derivable by a learner who knows the constituent meanings (though it is domain-specific).

Etymology

Oenothera biennis is the name of a plant whose bright yellow flowers open in the evening. People called it 'evening primrose' because of that sight, so the name now means the plant with flowers that open in the evening.
