Appearance
''Glyceria canadensis'' is a species of perennial bunchgrass which can grow up to 1m tall. The leaves are between 3-8 mm wide, as with other species in the genus ''Glyceria'' the leaf sheaths are fused for the majority of their length.Flowers are produced in a panicle typically between June and September depending on location. The panicle is typically open, containing few spikelets and each spikelet tends to droop giving the overall inflorescence a curved shape. Each spikelet is 3-5mm long and contains 5-10 individual florets. The lemmas are 2.9-4mm long.
''G. canadensis'' hybridizes with ''Glyceria grandis'' to form the hybrid ''Glyceria canadenis × grandis''. This hybrid is very similar to ''G. canadensis'' but with spikelets containing between 3-6 florets as opposed to 5-10 found in ''G. canadensis''. The hybrid occurs in the same habitat as ''G. canadensis''. This hybrid has been recognized by some authors as ''Glyceria laxa''.
