Rumex altissimus Smooth Dock is one of about 200 species of Rumex. Considered a noxious weed in Iowa. Most of the specie is considered weedy an invasive. Lepidoptera species (moths and butterflies) feed on many Rumex varieties as well. They are erect plants, usually with long tap roots. The fleshy to leathery leaves form a basal rosette at the root. The basal leaves may be different from those near the inflorescence. Propagate by seed.
