The Blueflower Butterwort (Pinguicula caerulea), a carnivorous plant of the southeastern United States, is one of Florida’s six butterworts. The cerulean or skyblue flowers are described by the species name caerulea. Pinguicula means fatty and describes the greasy feeling leaves that secrete mucilage in which small insects get mired. Milk poured over butterwort leaves curdles into a tasty yogurt-like solid. The common name may originate from this practice rather than describing the buttery-feeling leaves.
