Rorippa sessiliflora, commonly known as Stalkless Yellowcress, is an annual herb native to wetland margins, floodplains, and moist, disturbed sites across the midwestern and eastern United States, from South Dakota to Texas and east to Maryland and Florida. It typically grows to a height of 10-60 cm with erect stems that bear small, yellow flowers from May to September. The flowers are not particularly showy, but they give way to thick, wedge-shaped siliques (seed pods) that are characteristic of the species.

Stalkless Yellowcress is valued for its ability to thrive in wet, disturbed soils, making it suitable for rain gardens and restoration projects where soil stabilization is needed. It prefers full sun to part shade and can tolerate a range of soil types, provided they are consistently moist. While it is not commonly used in ornamental horticulture, it can be a useful plant for naturalized areas or wildlife gardens. Care should be taken when introducing it to new areas, as it has the potential to become invasive outside its native range.CC BY-SA 4.0
