Streptanthus cordatus is a species of flowering plant in the mustard family known by the common name heartleaf twistflower. 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.
Heartleaf twistflower has good disease resistance and is generally not prone to illnesses. However, it can be susceptible to pests and diseases present in its surroundings, and these infections are usually not severe. In terms of care, the plant requires a moderate level of maintenance. It should be pruned regularly to keep a tidy appearance and support healthy growth, and fertilizing can help encourage flowering. Heartleaf twistflower is suitable for anyone with outdoor space, such as a garden or patio, and does not need extensive care experience. It may, however, require more attention when grown indoors.
