There are many species of Spikerush (Eleocharis spp.) but in general, they are small and look similar to other rushes, grasses, or sedges. Slender spike rush can grow completely underwater and appear as a submerged plant. Spikerush is an erect plant with a single stem and no leaves. The stem is square in cross-section. The terminal seed head appears scale-like, with short white hairs often visible. Spikerush can form dense stands in shallow water.
Spikerush can be controlled by cutting or removing it.
