This winter or summer annual produces a rosette of leaves in its first year. The flowers are borne on erect, bristly-hairy, spreading branches. Reproduction is by seeds, that germinate in late summer to early spring. Leaves are alternate, sharply lobed or divided, with wide irregular wavy-toothed segments. Both leaf surfaces are hairy. The leaf tip is the largest, most distinctly toothed segment of the leaf. The small yellow flowers are produced in clusters at the ends of elongated stems from June through September. Each flower has 4 sepals and 4 yellow petals. Hedge Mustard is found through-out most of the United States. It is a weed of nurseries and agricultural crops. It grows best on dry, nutrient-rich soils in cultivated and disturbed sites.
