Botanical Description

Setaria parviflora, the knot-root bristlegrass or marsh bristlegrass (commonly listed under various names including feather pennisetum), is a tufted perennial grass of the Poaceae family native to the Americas, from the southern United States through Central America and the West Indies into South America. From short, knotty rhizomes the plant produces erect or ascending culms thirty centimetres to well over a metre tall, often branching at the base. The narrow, flat to folded leaf blades are five to thirty centimetres long with a tapering tip. In summer and autumn the inflorescence emerges as a dense, cylindrical, spike-like panicle three to ten centimetres long, in which each small ovoid spikelet is subtended by up to a dozen long, slender, golden-yellow or purple-tinged bristles that persist on the rachis after the seeds have fallen. The species favours moist or seasonally wet, sometimes saline habitats including marsh edges and ditches.
