Carex Hystericina- Porcupine Sedge

Carex Hystericina- Porcupine Sedge, more commonly called porcupine sedge, has a spiky seed head that some say reminds them of a porcupine. This light-green sedge grows well in USDA zone five to seven. In fact, except for the southeast and Nevada and Utah, this plant is found growing in marshlands and wetlands throughout the continental United States. It grows up to two feet in height, and it has unbranched triangular culms that are 0.75 inches to 2.5 inches long. Each culm has two to three light to medium green leaves shooting up along with older withered leaves near its base. Fertile culms end with a 0.75-inch to 1.75-inch long terminal spikelet surrounded by two to three other spikelets. Each spikelet is about 0.75-inches across. These spikelets are light green in the spring and summer. The blooms only last about ten days before the plant releases its pollen. As soon as the powder is released, the spikelets turn a light brown color. The plant takes its name because the spikes resemble quills on a porcupine. The leaves on this plant are between six and 10 inches long. They lay on alternating sides of the club, and it is not unusual for the broad leaves to be taller than the spikelets. The upper surface of each leave is smooth while the underside is rough. This wetland plant prefers partial shade, but it will tolerate full sun. It will tolerate being grown in a variety of soils including clay, loam, silt or sand. While it prefers to be wet constantly, it will tolerate brief periods without any moisture. It will also tolerate short periods of being submerged in water. This wetland plant grows naturally in many wetlands throughout the United States. When the plant is young, new ones start by the wind pollination, but as the plant matures, it is often spread by rhizomes. Carex Hystericina- Porcupine Sedge
