Tall Manna Grass

Tall Manna Grass

Tall Manna Grass
Genus: Glyceria
Species: maxima

Glyceria maxima is an invasive wetland plant. The stems are tall, up to 2 meters or more, and the leaves are up to 15 or 20 mm wide. For those with a little familiarity with grasses it is clearly a Glyceria and might be mistaken for G. grandis, since G. maxima is not yet included in many of our regional floras.
