Probably due to their unique and resplendent colors, I would say there are two top Japanese ornamental grasses that rival each other in popularity – the Japanese red blood grass and Japanese yellow forestgrass.
Of the two, only one is indispensable to a complete Japanese garden image – the forestgrass. In addition to its bright yellow hue, the Japanese forestgrass displays as a flowing cascading ornament unmatched in the world of grasses.
Varieties of yellow hairgrass and sedgegrass are more hardy versions. They can be used to accent a garden or garden area with a simple placement in the foreground of any garden area as pictured above.
