Eleocharis acicularis is way more common in the hobby than most people think. Another North American native, it is found along the shores of ponds, lakes and canals. It forms a dense bright green carpet, partially submerged or exposed to the air. Whether it should be collected in the wild by aquarists or not is open to debate. Probably, half the people who think they have Eleocharis parvula actually have E. acicularis. The two are difficult to distinguish. I believe the only way is to observe the flower and seed heads they make. It seems to grow slowly in my tank, I've had it for a month and a bit and I don't have a good carpet yet...but I am sure it will in time.

Eleocharis is one of my favourite plants! Make sure you have (a) Good lighting; (b) Substrate that is fine but nutrient laden; (c) Animals that don't burrow or dig; (d) Animals that won't eat it. I found that a fine, nutrient laden substrate will enable the plant to grow and spread. Without it, the heavier substrates will hinder growth and eventually kill the plant. Make sure you have good water movement on the plant to keep algae at bay. Shrimp and Otocinclus will keep it clean without eating it. CO2 (pressurized or liquid) and good lighting will really help this plant take off. I planted small bushels in my 265 L and it's taken off like wildfire!
