Pennsylvania bittercress flowers are 1/8" across with 4 light green, oblong sepals that cup the corolla, 4 white petals, 6 cream-colored stamens, and a single robust pistil with a flat, disc-shaped stigma. Fruits are erect, elongate (up to 1.25" long and 1 mm wide), flat-ended cylinders (siliques) containing a single row of seeds that emerge from the center of a fertilized flower while the petals persist.
