Carex scoparia Schkuhr ex Willd.
Broom sedge (Carex scoparia) is a long-lived, perennial sedge that is native to North America. It may have been introduced to New Zealand as a contaminant of pasture seed and was first recorded in the wild (naturalised) in 1948. The plant forms dense tufts with narrow, bright green leaves and flowering stems up to about 1 metre tall. It flowers from October to January, producing many small, densely clustered green flower spikes, which develop into small, dry fruits containing a single seed. It tolerates damp conditions and a range of soil types. It reproduces by seed. Seeds are dispersed by water, animals and human activities.
