Needle Hairgrass
Eleocharis acicularis
Family: Cyperaceae
Eleocharis Acicularis, Needle Hairgrass, produces extremely fine, hair-like leaves that are noticeably thinner and longer than the closely related E. parvula, creating a delicate, windswept grass carpet effect. It requires good light and CO2 to spread vigorously via runners; without injection it grows slowly and sparsely. Regular trimming keeps the carpet dense and lush.
