Also called Northern manna grass, Northern Mannagrass, Boreal Glyceria, Boreal Mannagrass, Boreal Manna Grass
Small floating mannagrass is a native aquatic grass that grows in wet mountain forests, ponds and streams, often floating or lying in shallow water. Keep its roots wet or submerged and give it open, sunny to lightly shaded conditions.
Glyceria borealis is a species of Glyceria known by the common names northern mannagrass, boreal mannagrass, and small floating mannagrass. It is native to much of the northern half of North America, where it has a widespread distribution. This semiaquatic plant grows in wet areas in mountain forests, often in the water.
It grows a tall and very thin stem often exceeding a meter in height when erect. It may bend, lie flat on the ground, or float in the water of ponds and streams. The leaves bear ligules up to a centimeter long. The narrow, long inflorescence has cylindrical spikelets one to two centimeters long, each made up of 6 to 11 florets with membranous margins.
