100 Seeds Spike Rush Eleocharis acicularis Dwarf Hairgrass Aquatic Pond Marginal Plant

Spike Rush (Eleocharis acicularis) is a fine-textured, grass-like aquatic perennial that forms dense tufts of slender, needle-thin green blades. It is prized by water gardeners and aquascapers for its carpeting habit and tidy, architectural look along pond margins, bog areas, and shallow water features.

This versatile plant works well as a foreground carpet in water gardens, as a softening accent around rockwork and container ponds, and as a naturalizing filler in consistently moist soil. It spreads gradually by runners to create a dense, low-growing colony and can be grown submerged or in saturated substrate.
