Distribution

Its native range is circumpolar throughout tropical, subtropical, subarctic, and temperate climate areas of the Northern Hemisphere and Southern Hemisphere.[4][1][5][6][7][8] [9] It is also widely distributed as an introduced species in suitable habitats worldwide. It grows in moist and muddy places, often in wetlands and riparian areas.[10]

In habitats where it is not native and has naturalized it may be considered a weed. The relationship of North America plants to the Eurasian Juncus ranarius is weakly delineated.[3]

Description

Juncus bufonius is an annual monocot that is quite variable in appearance. It is generally a green clumping grasslike rush, with many thin stems wrapped with few threadlike leaves.[3]

The flowers are borne in inflorescences and also in the joint where the inflorescence branches off of the stem. It is a grassy flower folded within tough bracts and sepals.[3] The blooming period is March through May.[10]
