Phyllostachys aurea (golden bamboo).
Abstract P. aurea is a highly invasive running bamboo native to Southeast China that is now widespread globally and especially problematic in Australia and North America. This woody, rhizomatous perennial grass rapidly forms a dense monoculture, suffocating other native plants and altering the entire ecosystem. As well as having detrimental effects on the environment this bamboo may also damage property and poses a potential threat to human health as it harbours a fungus responsible for the disease Histoplasmosis. Invasive bamboos are among the fastest growing plants on Earth and one infestation of P. aurea can spread as far as 9.3 miles. The spread is rapid in all directions, increasing each successive year. It is listed as invasive in Australia, New Zealand, Hawaii, Reunion, Brazil, Costa Rica, Cuba, USA, Mexico, Spain and France. In the United States, it is listed as naturalized or invasive in 273 counties including the mid-Atlantic region of the USA, Pennsylvania, Maryland, Virginia, West Virginia, and Georgia. It is reported as fully naturalizing in New Zealand, with infestations forming dense stands, and some invading national parks. In Australia, this species is regarded as an environmental weed in Queensland and New South Wales.
