Pholistoma auritum is a species of flowering plant in the borage family which is known by the common name blue fiestaflower.
Pholistoma auritum is an annual herb with a brittle, fleshy, bristly stem branching profusely, sometimes forming a tangle. The leaves are deeply lobed and toothed and borne on winged petioles. The foliage is coated in hairs and bristles. The inflorescence is made up of one or more widely bell-shaped flowers up to 1.5 centimeters long and 3 wide. The hair-lined flowers are blue to purple with darker markings in the centers.
The purple Arizona fiestaflower, Pholistoma auritum var. arizonicum, is considered a subspecies.
