marsh arrowgrass, Triglochin palustris

Marsh arrowgrass' palustrine habitat stretches around the globe in the northern hemisphere. I'm sure you've seen them! No? Well then get out there in the wetlands and pay attention! You'll have to in order to notice these smallish plants. In this image, the flowers are the fuzzy bits to the lower left. The advantage of seeing the oblong pods is that you can know it's not the sister species, seaside arrowgrass, that has rounder pods. The field of this image takes in an inch or so, so look close while you're out there. Arrowgrasses were occasionally eaten as greens or dried and used like coffeee by Native Americans. But they are toxic for livestock. Marsh arrowgrass grows in AK, AZ, CA, CO, IA, ID, IL, IN, ME, MI, MN, MT, ND, NE, NH, NM, NV, NY, OH, OR, PA, RI, SD, UT, WA, WI, WY, in all of Canada, and on GL and SPM.
