Morphology
The compound is a straightforward noun+noun composition: 'needle' describes the fine, needle-like leaves and 'rush' names a grasslike marsh plant, so the meaning of a rush with needle-like leaves is directly derivable from its parts. This kind of transparent descriptive compound follows common word-formation patterns (and parallels in other languages), so a B1 learner who knows both constituent words would readily infer the MWE's meaning.
Etymology
Needle rush gets its name because its thin leaves look like needles and it is a kind of water plant called a rush. That's why the name helps you remember this thin, rush-like plant people put in aquariums to 'add oxygen to the water'.
