IdentificationTumble Mustard is an annual up to 6 (-9) feet tall with horizontally spreading branches. The basal leaves form a rosette of leaves that are oblanceolate or lanceolate in outline, these cut into lobes of various widths. The stem leaves are similar but the lobes are narrower (many linear). The inflorescences terminate the branches, eventually becoming long and many-fruited. Flowers are yellow, fruits are divergent from branches, long, relatively straight to slightly curved. S. officinale is similar but the pods are only 1/3 as long and are appressed to the branch.
