Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.

  • Description

  • Notes

Japanese Bloodgrass has very vertical leaves that emerge bright green with wine-stained tips. Foliage becomes increasingly red as season progresses, turning copperish in winter. It is a lovely grass providing great vertical interest and a lovely color contrast, but it is invasive and will spread, choking out smaller plants and tangling with larger ones. Best used in confined areas or containers.
Cut back in late winter to early spring, just as new foliage is emerging. Due to its spreading tendencies, it is best suited to large areas as a ground cover, in containers, or confined between walks, drives, and buildings. It absolutely will spread.
