Fiber optic grass
This little sedge gets it's name from the fact that the tiny white flowers look like little fiber optic lamps. It grows to about 30 cm wide an will thrive in either the sun or the shade but it must be kept moist. it can even be planted in water. It is perfect for a water feature where it will be splashed or even in a pond. The 'moplike' tufts are upright when the plant is young and they become longer with age. They can be given a 'haircut' if necessary. The name is derived from the Greek isos - equal; lepsis = scale; referring to the glumes of the flower.
