Morphology
viper's + grass
Although a learner who knows 'viper' (a snake) and 'grass' (a plant) might infer this is some plant associated with vipers, they would not be able to derive the specific botanical meaning — a perennial with long edible black carrot-like roots — from the constituents. 'Viper's grass' is a conventional common name whose detailed referent is arbitrary/historical rather than compositional, so its full meaning is not predictable for a B1 learner.
Etymology
Viper's grass may get its name from the plant's long dark roots that look like little 'vipers'. One popular story says people once used the plant to treat snake bites, so the name links the plant to snakes.
