Japanese Bloodgrass is a variety of cogongrass which has been designated as one of the 10 worst weeds in the world. While the red form is not invasive, it can revert back to the 4-5 foot tall green form which is extremely aggressive. Cogongrass has already invaded 153 billion acres worldwide, and over one million acres in Florida, where it has displaced many native species of plants.
