Morphology

wool + grass

The noun compound transparently signals a grass that is wool-like — combining 'wool' (soft, fluffy) with 'grass' gives the clear idea of a grass with woolly or fluffy appearance, so a B1 learner who knows both words can infer the general concept. However, the specific botanical details (tall habit, white-ribbed leaves, plume-like flower heads like pampas grass) are not fully predictable from the constituents, so the relation is only partially transparent.

Etymology

Wool grass comes from tall, decorative grass whose large, soft flower plumes look like white wool. That's why gardeners call these plants 'grass with wool-like plumes' today.
