It grows from late March or early April until fall from short, knotty, branching rhizomes. Foliage is a distinctive whitish green. The base of the plant is slender and wiry. It produces two and sometimes three seed crops during one growing season the first one during May or June. Bristles are left along the seed stalk after the seeds disseminate. It grows best on moist or wet sites. In Florida, it grows on wet sandy soils, sloughs, and acid flatwoods. In Texas and Louisiana, it grows well on salty prairie sites; also grows on salt marshes if water level is relatively low.
This species is widespread throughout North America, South America, Europe, Southeast Asia, Australasia and less frequently in South Africa.
