Also called Austrian Field Cress, Austrian Yellow Cress, Austrian Cress, Austrian Fieldcress, Field Yellowcress
Austrian yellowcress is a perennial herb in the cabbage family, native to central and eastern Europe and parts of Asia, that grows upright to about one metre tall. It thrives in disturbed ground, roadsides and wet mudflats, and is often treated as a weed.
Rorippa austriaca is a species of flowering plant in the family Brassicaceae known by the common names Austrian yellow-cress and Austrian fieldcress. It is native to parts of Europe and Asia, and it is known in North America as an introduced species and sometimes a noxious weed. It can grow in disturbed habitat, such as roadsides, and in very wet habitat such as mudflats. It is a perennial herb growing upright to erect, reaching a maximum height near one meter. The branching stem bears hairless blue-green lance-shaped leaves up to 10 centimeters long. The bases of the upper leaves clasp the stem. The inflorescence is a raceme at the top of the stem and the ends of stem branches. The mustardlike flowers have small yellow petals. The fruit is a plump silique a few millimeters long, but many plants do not fruit and seed production is rare.
