The flowers of Pinguicula caerulea are bluish-purple (the word caerulea means "sky-blue" in Latin). Here one flower is seen from the front, one from the side. Notice the small spur on the flower seen in side view. As with Pinguicula lutea, the flowers of Pinguicula caerulea are wide enough to admit a bee, and a long-tongued bee can, when it fully enters the flower, suck nectar from the spur.
