Cyperus eragrostis
Also called Pale Galingale, Umbrella Sedge, Drain Flat Sedge, Tall Cyperus, Pale Galingale, Tall Flatsedge, Tall Flat Sedge
Tall flatsedge (Cyperus eragrostis) is a tufted, sedge-like perennial that looks like grass and is often found in wet, open, disturbed ground. It grows best in full sun with consistently moist to saturated soil.
Cyperus eragrostis is a species of sedge known by several common names, including tall flatsedge, nutgrass, tall nutgrass, umbrella sedge, chufa, Earth almond, zula nuts, edible galingale and pale galingale. In New Zealand, it is also known by the Māori name Puketangata. This species is associated with disturbed wet environments.
Cyperus eragrostis occupies various habitats around the world. It thrives in wet, open, disturbed environments made up of hydric soils (saturated soils) such as wetlands, ditches, roadside ditches, riverbanks, ponds, swamps, floodplains, mud flats, shallow vegetated channels in pastures and fields, sandflats, and muddy lake edges. This species is a heliophilous plant, which means it thrives in areas of high sunlight and minimal shade. It is also sensitive to salinity (dissolved salts in water) and prefers moderate to high nutrient-rich soils with a neutral pH. Cyperus eragrostis is also able to establish itself in clay-loam and sandy-loam soils, making it easy for it to spread and reproduce. Cyperus eragrostis gets its nutrients through its roots so therefore the species prefers mesotrophic soil (soil with balanced nutrients) with a high richness of organic matter. With all these reasons combined, Cyperus eragrostis has been able to establish itself easily all around the world in both natural and modified environments.
