Straw-colored Flatsedge
Cyperus strigosusAlso known as False Nutsedge
Straw-colored flatsedge anchors damp soils along wetlands, ditches, and cultivated ground, spreading via short rhizomes with bulbous corms. Its radiating umbels of golden, linear spikelets mature in late summer, providing nutrient-rich seeds for waterfowl and small songbirds. Triangular stems and long leafy bracts make it an adaptable pioneer plant that quickly colonizes newly exposed mudflats.
