Morphology
The phrase is compositional: 'cotton' modifies 'grass' to indicate a grass with cotton-like, fluffy seed heads and 'common' simply marks it as a widespread/typical species. This attributive use of a material word to signal resemblance is predictable and cross-linguistically common, so a B1 learner who knows the constituents can infer the meaning.
Etymology
Common cotton grass gets its name from how the plant looks. Its white, fluffy seed heads look like cotton, it grows like grass, and 'common' means 'found in many places', so the name helps you picture this marsh plant.
