Arabis glabra is a wildflower plant, often called Tower Mustard. It is found in the United States in the northeast, and some of the plains states and as far south as Kentucky. It grows in open fields and woodland clearings, as well as along ledges... usually in dry soil.

It has an erect habit, with basal leaves resembling dandelion, but rougher, and pointed leaves surrounding the long, unbranched stems. Pale yellow blooms occur in the spring, turning to long upturned seed pods over the summer season.

Regional...

This plant has been said to grow in the following regions:
