Morphology
The compound 'tree onion' is compositionally transparent: a B1 learner who knows 'tree' and 'onion' can infer it denotes a kind of onion associated with a tree-like or plant growth habit (i.e., a type/variety of onion). This is a straightforward noun+noun subtype formation rather than an idiom or metaphor, so the meaning is predictable from the constituents.
Etymology
The plant tree onion gets its name from the way it grows small round onion 'bulbs' at the top of a tall stalk, looking like a tiny tree of onions. So the name helps you remember that it is 'an onion that makes little bulbs' often used fresh in salads.
