Japanese Blood Grass
Japanese blood grass is a slowly spreading rhizomatous grass. The young upright blades are green at the base with red tips. The red color increases and deepens through the growing season. This grass rarely blooms, being grown for the color of its leaves.
If Japanese Blood Grass is located in fertile, moist soils, there is a possibility of rampant growth bordering on invasiveness. However, Japanese blood grass is not consistently hardy in Colorado Springs, overwintering only in warm, protected microclimates.
