Rottboellia campestris, commonly known as Itch Grass, is a semi-deciduous grass native to central and southeastern United States. It typically inhabits open grasslands and disturbed areas, often colonizing areas with well-drained soils. This species is known for its rapid growth, reaching heights of 1-6 feet (0.3-1.8 meters). Itch Grass has a coarse texture with stiff, upright stems and flat leaves that can cause skin irritation upon contact, hence the common name.

Itch Grass is valued for its ability to quickly cover ground and is sometimes used for erosion control in tropical regions. However, its aggressive growth habit and potential to cause skin irritation make it less desirable for ornamental use. In cultivation, it thrives in full sun and adapts to a variety of soil types, including clay, loam, and sandy soils, provided they are well-draining. It requires medium amounts of water and can tolerate drought once established. Due to its invasive nature, it is important to monitor and manage its spread to prevent it from becoming a problem outside its native range.CC BY-SA 4.0
