Dicoria canescens forms thickets of many individuals in the desert sand. The distinctive lower leaves are long, pointed, sharply toothed, and covered in a coat of thin white or gray hairs. The upper leaves are smaller and more rounded. One plant can produce several whitish flower heads containing disc florets but no ray florets. Sometimes the heads form closely associated pairs, a characteristic which is the origin of the common name "twinbugs".[6][7][8][9]
