Rattlesnake Grass
Glyceria canadensis
Rattlesnake Grass, also sometimes called Rattlesnake Manna Grass, is a valuable addition to wetlands and rain gardens, forming dense clumps of slender, arching green leaves. In early summer, it produces graceful, open seed heads that rattle in the breeze, lending the plant its common name.
