Quote:
Cogon grass (Imperata cylindrica), a perennial grass from southeast Asia, is considered one of the 10 worst weeds in the world. Covering billions of acres worldwide, it is well established in the southern United States as far north as Virginia. Cogon grass was accidentally introduced to the United States early in the 20th century as packing material in Japanese orange crates. It was first found growing wild in Alabama in 1912. Later in the century, it was purposefully imported from the Philippines as a forage grass, but it didnít measure up as fodder. The cultivated variety ĎRed Baroní, or Japanese Blood Grass (Imperata cylindrica var. rubra), originally thought to be sterile and widely sold as an ornamental plant, has been found to revert to an aggressive, green form, and even in its red form, to produce fertile seed and new seedlings. Because I. cylindrica is a listed Federal Noxious Weed, a federal permit is required to move it interstate...
