Aristolochia baetica is a noteworthy herbaceous vine characterized by its sizable, heart-shaped green foliage. During early summer, it produces elongated, tubular flowers that exhibit a dark red-brown hue and bear a resemblance to saxophones. The flowers emit a strong odor, which serves to attract flies for pollination. Following this, the plant generates large, brown seed pods that are barrel-shaped and ribbed.
