Barbarea orthoceras, commonly known as American yellowrocket, is a perennial herb native to moist meadows, streambanks, and wetland margins in North America, particularly in the western United States and parts of Asia. It typically grows to a height of 24 inches (61 cm) with branching stems that bear clusters of bright yellow, four-petaled flowers from late spring to early summer. The foliage consists of basal rosettes of oval leaves with rounded lobes, while the fruit is a narrow silique that can reach up to 2 inches (5 cm) in length.

American yellowrocket is appreciated for its vibrant yellow flowers and its ability to thrive in wet conditions, making it suitable for rain gardens and areas with poor drainage. It is also valued for its edibility; the leaves can be consumed raw or cooked, offering a peppery flavor, and the roots are known for their horseradish-like taste. This plant is relatively low-maintenance, requiring consistently moist soil and full sun to part shade. While it is not commonly afflicted by diseases, it can be susceptible to pests such as flea beetles. In some regions, it may spread aggressively and should be monitored to prevent unwanted naturalization.CC BY-SA 4.0
