Status

Hidden Bittercress is a non-native mustard from Eastern Asia that has been introduced throughout the eastern United States. In Maryland, it has been found on the Coastal Plain and Piedmont. Hidden Bittercress favors disturbed habitats, often in moist soils, like ditch edges, and low wet areas.

This species has often had the European Cardamine flexuosa Withering missapplied, a taxon that now is excluded from the Maryland flora.

Description

Hidden Bittercress can be identified by having compound stem leaves with the terminal leaflets that are broader than the lateral leaflets. The stems are flexuous, which means the stems have a zig-zagging nature, unlike Pensylvania Bittercress that has straight erect stems. Narrowleaf Bittercress also has erect straight stems and acuminate leaflets.
