Tall Flatsedge
Cyperus eragrostisAlso known as Pale Galingale, Umbrella Sedge, Tall Nutgrass, Puketangata
Tall flatsedge thrives in damp, disturbed soils along streams, ditch margins, and marshy meadows. Recognized by its pale green umbrella-like bracts surrounding dense clusters of golden-brown, flattened spikelets, this perennial grass-like plant forms robust clumps. Waterfowl and small mammals consume its seeds, while the dense root structure helps stabilize muddy shorelines.
