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.
Japanese blood grass has been growing at the Xeriscape Garden for many years. It has been an easy-care and colorful plant.
Japanese blood grass overwinters best in a warm, protected micro-climate in the Colorado Springs area.
This plant requires little maintenance. Cut back after the first fall freeze or in late winter since it doesn't have much winter interest.
