Morphology
curly + grass
The meaning is compositionally approachable—'curly' + 'grass' will lead a B1 learner who knows both words to expect a plant (grass-like) with curled or spiraling leaves, so the basic idea is inferable. However, the lexicalized meaning refers to a specific small fern (not a true grass), a taxonomic/detail that cannot be predicted from the constituents, so full understanding requires exposure.
Etymology
Curly grass got its name because its many small, spiral leaves look like tiny, curly grass, so early observers called it that. That's why today curly grass means a small 'fern' with many spiral leaves growing in tight clumps.
