Other info. - This showy species is rare in Missouri, being found in only one or two counties in the Ozarks. This species is common in the Coastal Plain of the eastern U.S. but is a glacial relict in out area. Missouri is an interesting state in the fact that it has many of these glacial relicts as part of its flora.
Another rare species, E. cuneifolium Willd. is similar but this plant lacks the fascicles of small leaves in its nodes and has broader leaves. E. hyssopifolium also has bigger, brighter flowers.
