Morphology
The phrase denotes a cottonwood tree that is black or dark in colour, which is directly and compositionally derived from 'black' (dark colour) + 'cottonwood' (the tree). This simple adjective + noun pattern is cross-linguistically common and involves no idiomatic or metaphorical shift, so a B1 learner who knows both constituents can infer the meaning.
Etymology
Black cottonwood comes from two clear images: the tree makes white, fluffy seeds that look like 'cotton', which gives cottonwood, and it has darker bark than other poplars, which gives black. So the name points to a tall North American poplar you can spot by its 'cotton-like' seeds and 'dark bark'.
