It is an erect leafy annual cabbage plant. It grows to about 1 m high. The plant can vary a lot. The leaves are elliptical and deeply divided. They are dark green. The end segment of the leaves is oval. The leaves taper towards the stem and have a strong mustard flavour. The flowers are pale yellow. They have 4 petals. It produces a flower and seed pods at the top. The seed pod is long and narrow. It is 3-5 cm long. The seeds are reddish-brown.
