Carex bicknellii can be found in North America from Eastern half of Canada and south to Kansas. It grows in dry and moist prairies, open woodlands and rocky areas. This Carex tolerates dry locations better than many sedges. It is useful for rain gardens, meadows, and areas where drought-tolerant plants are required. Bicknell’s Sedge grows in tufts of green, narrow, grasslike foliage and spreads by rhizomes. Copper-colored, oval-shaped seedheads appear in late spring giving it one of its common names.

A common sedge able to grow almost anywhere, most often found in the wild in dry, disturbed areas.

The leaf sheaths at the base of each blade has an unusual whitish color and an almost glassy appearance. In late spring multiple leafy culms rise above the foliage to 3-4’. Each culm bears 2-6 oval flower spikes. Each green spikes contain upper pistillate and lower staminate florets. The spikelets are tapered at the base and bluntly pointed at the tip.
