Scirpus cyperinus (L.) Kunth.
A perennial, densely tufted sedge with stems up to six feet tall. The sturdy stems are smooth and more or less round with about 10 stem leaves above a fountain of large, slender, basal leaves. Sheaths are brownish or green and not tinged with red. Several to many rays of the inflorescence ascend from a fountain-like base and contain one to many tiny spikelets in small, compact clusters at the apex of the stem. Many brown, woolly bristles surround the nutlets, giving the cluster of spikelets a fuzzy appearance.
Found in swamps, marshes, wet meadows and banks of ditches. It is often prominent in roadside ditches. Grows in wet soil or shallow water.
Seed - sow in saturated potting soil barely covering the seed. Seed usually germinates fairly quickly.
