Andropogon virginicus | |
Andropogon virginicus is a species of grass known by several common names, including broomsedge bluestem, yellowsedge bluestem and (in Australia, because it was introduced to that country after being used as packaging for bottles of American whiskey) whiskey grass. It is native to the southeastern United States and as far north as the Great Lakes. It is known as an introduced species in California and Hawaii, where it is weedy.
Andropogon virginicus has also been introduced to Japan and Australia. It competes with other species by allelopathy, releasing persistent herbicidal chemicals from its dying tissues, such as decaying leaves. [2] [3] [4] A. virginicus colonizes disturbed areas such as abandoned mining sites. It is a weed of pastures and grazing ranges, where it proves less palatable and nutritious to cattle than other grasses. [2] This species is tolerant of fire and grows back quickly and more abundantly after a burn. [2] It is perhaps most problematic in Hawaii, where its natural growth patterns are out of synch with the local climate. It is dormant during the Hawaiian rainy season, dying back and leaving the slopes it has colonized exposed and vulnerable to significant erosion. [5] Despite its weediness, the grass is sometimes grown as an ornamental plant. [6]
The species is now considered invasive in New Caledonia and is stated in legal texts. [7]
The species features on the list of Invasive Alien Species of Union Concern. [8] [9] This means that import of the species and trade in the species is forbidden in the whole of the European Union. [10]
Andropogon virginicus is a perennial grass forming narrow clumps of stems up to just over a meter in maximum height (around 3 feet 3 inches). Its stems and leaves are green when new, turning purplish to orange and then straw-colored with age. It produces large amounts of seeds small enough to disperse on the wind. This grass is successful in a wide range of habitats. It is a prolific seed producer, it has a high germination rate and seedling survival rate, and it thrives in poor soils. [2]
Andropogon virginicus has been used as the straw base for the production of handmade brooms in the southeastern United States. [11]

Lespedeza cuneata is a species of flowering plant in the legume family known by the common names Chinese bushclover and sericea lespedeza, or just sericea. It is native to Asia and eastern Australia and it is present elsewhere as an introduced species and sometimes an invasive plant.
Andropogon ternarius is a species of grass known by the common names split bluestem, splitbeard bluestem, silver bluestem, and paintbrush bluestem. It is native to the southeastern, east-central, and south-central parts of the United States, where it occurs from New Jersey south to Florida and west to Kansas, Oklahoma, and Texas.

Themeda quadrivalvis is a species of grass known by the common names grader grass, habana grass, and kangaroo grass, not to be confused with Themeda triandra, which is also known as kangaroo grass. It is native to India, Nepal, and Malaysia. It can also be found in many other places as an introduced species and often a noxious weed. It occurs in the United States, New Caledonia, Fiji, Mauritius, Thailand, Indonesia, Papua New Guinea, China, the Middle East and tropical America. It is a troublesome exotic weed in Australia, especially in northern regions. It is also an agricultural weed in crops such as sugar cane and lucerne.
Schizachyrium condensatum is a species of grass known by the English common names Colombian bluestem, bush beardgrass, and little bluestem, and the Spanish common names aguará ruguay and yerba barbuda. It is native to South America, and it is well known in other places as an introduced species and noxious weed, particularly in Hawaii.
Brachiaria mutica is a species of grass known by the common names para grass, buffalo grass, Mauritius signal grass, pasto pare, malojilla, gramalote, parana, Carib grass, and Scotch grass. Despite its common name California grass, it does not occur in California; it is native to northern and central Africa and parts of the Middle East, where it is cultivated for fodder. It was introduced elsewhere and it is now cultivated throughout tropical regions of the world for this purpose.
Cyrtandra heinrichii, known as ha'iwale or lava cyrtandra, is a perennial flowering plant in the family Gesneriaceae. It is found on the Hawaiian island of Kauai.
Escaped plants are cultivated plants, usually garden plants, that are not originally native to an area, and due to their dispersal strategies, have escaped from cultivation and have settled in the wild and bred there, whether intentionally or unintentionally. Escaped plants are purposefully introduced plants that have naturalized in the wild and can develop into invasive plants, the settlement of which is to be assessed as problematic. Other commonly used terms include escaped garden plant, garden escapee, escaped ornamental or garden refugee.
