Imperata cylindrica 'rubra', or Japanese Blood Grass is a low growing deciduous grass with an upright habit to 1 ft tall. The vertical leaf blades emerge a lime-green color in spring with a hint of red at the tips. As the season progresses a cranberry-red color progressively works down towards the leaf base. This process repeats itself when the plant goes dormant with a gray-brown color at the tips working down towards the leaf base. Your grass will soon go dormant. You can leave the foliage alone to add winter interest to your garden, or you can cut the spent foliage down to ground level. Next spring new blades will grow from the roots.

p.s. - thanks for the compliment!
