Morphology

black + locust

The meaning is directly compositional: 'black' (color) + 'locust' (a tree species or its wood) denotes the wood or tree called the black locust. This follows a common color+noun descriptive pattern found across languages, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Black locust may come from early European settlers who thought the tree's long seed pods looked like the European 'locust bean', so they used locust and added black for the tree's dark bark. That's why black locust means this particular tree.
