Try these ideas when landscaping with ornamental grasses. In areas with warmer winters, this ornamental grass spreads aggressively through rhizomes and self-seeding—to the point where it displaces other species. It is reported to be less aggressive in cooler climates. Watch plants carefully for any specimens that revert to all-green foliage. These rogue green plants are especially invasive and should be eradicated immediately. Japanese bloodgrass is listed as a Federal Noxious Weed under the Plant Protection Act, which means it can’t be imported or transported between states without first obtaining a federal permit. In addition, it has been declared a noxious weed in warm-weather states including Alabama, Florida, Georgia, Hawaii, Mississippi, North Carolina, and South Carolina. Check your state law before purchasing or planting one. Keep your ornamental grasses thriving using these tips!
