Cottongrass bulrush or wool grass is a densely-tufted, clump-forming perennial, 3-6 ft. high, with an erect stem that is leafy up to the flower cluster. Many brown, woolly bristles surround the nutlets giving the cluster of spikelets in the terminal inflorescense a fuzzy appearance. A compound umbel, made up of many spikelets on branching rays, is at the top of a triangular or nearly round stem and is surrounded by spreading green, leaflike bracts; spikelets wooly in fruit.
