Other info. - This somewhat showy yet weedy species can be found throughout Missouri and is the most common member of the genus in the state. The plant is incredibly variable and sometimes be difficult to identify using botanical keys. Some authors separate the different plants into their own taxa but further study is needed on this plant. Different populations of plants seem to bloom at different times of the summer also, further confusing the issue. For the most part, E. virginicus can be partially identified by its erect inflorescences, glaucous nodes, and clustered spikelets.
