Native from eastern Europe to Siberia, first collected by L. H. Bailey in 1887 as adventive near Lansing, Ingham Co., also collected by F. J. Hermann in 1936 as well established in a moist meadow in the Nichols Arboretum in Ann Arbor, Washtenaw Co. Apparently now becoming somewhat weedy in parts of Wisconsin, and recently collected in Alger Co.
This is a coarse plant with distinctive glandular-warty stems. It is sometimes cultivated as a green and occasionally advertised as "perennial broccoli," although there are also apparently perennial strains of true broccoli (Brassica oleracea).
