The gloss rocket is a fresh green, wintering green, annual herbaceous plant that reaches heights of 10 to 50 centimeters. The independently upright stem is branched. The leaves have one to six serrated, pinnate to cleft sections and a larger, spear-shaped end section.

The flowering period in Central Europe extends from May to June. The umbrella-cluster inflorescence contains many flowers. The hermaphrodite flowers are fourfold. The four sepals are 2 millimeters long and unhorned. The four pale yellow petals are 2 to 4 millimeters long. The stamens are 0.7 millimeters long.

The young pods protrude considerably above the flowers, later they are 3 to 5 centimeters long and stand on 5 to 10 millimeter long, thin stems.

Base chromosome number is x = 7; there is diploidy , so 2n = 14.

It grows here in the societies of the Sisymbrion Association. In southern Europe she is a character species of the Hordeion association.

The gloss rocket thrives best on loose sand - or clay soils , which should be rich in bases and nitrogen . It settles in vacant locations in port facilities and in the area of ​​freight yards in areas with mild winters and dry and warm summers.
