Blue sedge (Carex flacca) is a long-lived, perennial sedge that is native to Europe, Asia and North Africa. It was introduced to New Zealand as a garden ornamental and was first recorded in the wild (naturalised) in 1883. The plant forms dense tufts with blue-grey leaves and flowering stems up to about 60 centimetres tall. It flowers from October to June, producing several slender flower spikes, which develop into small, dry fruits containing a single seed. It tolerates drought, damp conditions and a wide range of soil types. It reproduces by seed and vegetatively from creeping rhizomes. Seeds are dispersed by water, animals and human activities. Rhizomes are spread by soil movement and other human activities.
