Green Bulrush
Scirpus atrovirens

a.k.a. Dark Green Bulrush

Green bulrush is a common, short-lived, pioneer, emergent, native perennial with course clump form and nice clusters of small, brown heads that may reach a height of 5'. It is well-suited to controlling erosion along shorelines, ditches, stream banks, meadows and thickets. It is a good pioneer species that will vegetate a site quickly with a decorative bunching form. It is a frequent pioneering colonizer of wetland mitigation sites and disturbed areas.
