Faits intéressants
Canada Mannagrass is an obligate wetland species, meaning that it can only grow in wetlands such as at the edges of streams, rivers, ponds, etc. Its spikelets stand out when planted with other grasses due to the way they form a graceful cascade. The spikelets also form a shape resembling a rattlesnake’s rattle, giving it its other common name Rattlesnake mannagrass.
