Juncus bufonius, commonly known as Toad Rush, is an annual monocotyledonous plant in the rush family Juncaceae. It is often found in moist and muddy places, including wetlands, riparian areas, and sometimes in disturbed sites such as ditches and wet agricultural fields. Its native range is extensive, covering tropical, subtropical, subarctic, and temperate regions across both the Northern and Southern Hemispheres. Toad Rush typically grows to a height of 10-60 cm and has a clumping growth habit with green, cylindrical, grass-like stems and threadlike leaves that may be inconspicuous.

Toad Rush is not typically cultivated for ornamental purposes due to its weedy nature and modest appearance. However, it can be useful in biofiltration systems and for erosion control in wetland restoration projects because of its tolerance to waterlogged conditions and ability to colonize bare mud. It prefers full sun to part shade and can grow in a variety of soil types, provided they are consistently moist. While it is not known for significant pest or disease problems, its potential for invasiveness should be considered before planting, as it can spread rapidly and outcompete native vegetation.CC BY-SA 4.0
