Morphology

slender + wild + oat

The noun phrase is fully compositional: a B1 learner who knows 'slender' (thin), 'wild' (growing naturally), and 'oat' (a cereal/grass) can infer it denotes a thin, naturally growing oat plant or species. There is no idiomatic or metaphorical shift — the meaning is a straightforward descriptive compound common across languages, so it is immediately understandable from its parts.

Etymology

The plant name slender wild oat describes the plant: slender for its thin, upright stems, wild because it grows outside farms, and oat because it is an oat. Because it often spreads into crop fields and competes with the crops, farmers call it a 'weed', so the name now means a thin oat plant that can invade fields.
