Streptanthus cordatus is a species of flowering plant in the mustard family known by the common name heartleaf twistflower.[1][2] It is native to the western United States, where it can be found in many types of sagebrush, woodland, and forest habitat. It is a perennial herb producing a branched or unbranched stem up to about a meter tall. It is often waxy in texture. The basal leaves are oval or spoon-shaped with bristle-toothed blades borne on rough-haired petioles. Leaves higher on the stem are oval to lance-shaped, up to 9 centimeters long with their bases usually clasping the stem. Flowers occur at intervals along the upper stem. Each has a calyx of sepals roughly a centimeter long which begin greenish yellow and mature purple. Four purple petals emerge from the tip of each calyx. The fruit is a thin, narrow silique which may reach 14 centimeters in length or longer.
