Tower Mustard may be found along the semi-abandoned forest road, parallel to the railway. In May, it gives a powerful, up to one meter height, straight and smooth stem-peduncle. In the lower part it is covered with bluish sessile lanceolate leaves. At the top, an inflorescence composed of small yellowish flowers is situated. The plant fade quite soon, and it is more difficult to see during the rest months of the year.
Tower Mustard indusion has antibacterial, antiinflammatory properties.
