Cardamine impatiens, the narrowleaf bittercress^[1] or narrow-leaved bitter-cress,^[2] is a plant species of the genus Cardamine belonging to the family Brassicaceae. It is a slender, biennial herb, that produces sterile leaves in the first year, one to several flowering stems during the next. Its leaves are pinnate with several pairs of lanceolate, dentate leaflets and a terminal, slightly longer leaflet. The short petals surpass the calyx by half of its length. The seeds are arranged in one row on each side of the central membrane of the narrow pod and are ejected out in a shower due to the tension formed as the seed pod (silique) dries. It grows on walls, open ground in shady places in forests usually disturbed by man.
