Abstract
Ipomoea carnea subsp. fistulosa is a species of morning glory that has been introduced worldwide as an ornamental and hedge (living fence) plant. The species has escaped from cultivation to become naturalized and invasive mostly in disturbed sites, riparian areas and wetlands, and it behaves as a weed in cultivated fields, such as rice plantations. It is a strong competitor for resources (e.g. nutrients and water), with the potential to outcompete native plants. The species has been listed as a noxious weed in the USA and as invasive in India, Nepal, Egypt, South Africa, Swaziland, Cuba, and in many islands in the Pacific region.
