Morphology
The noun is transparently built from modifiers plus a head: 'needle' (needle-like), 'spike' (spike-like stalk/inflorescence) modifying 'rush' (a grasslike marsh plant), so the phrase denotes a rush with needle-like spikes — an aquatic plant. This kind of descriptive compounding is a common, compositional pattern in English (and similar in other languages), so a B1 learner who knows the parts would readily infer the general meaning.
Etymology
Needle spike rush comes from how the plant looks: it has very thin, needle-like leaves that grow on a pointed spike, and it is a water plant called a rush. That's why the name helps you remember it is a thin, upright water plant often used to add oxygen to aquariums.
