Pinguicula primuliflora ( /ˌpɪˈŋgwɪkjələ ˌpɹɪmjʊləˈfloːɹə/ ), commonly known as the southern butterwort or primrose butterwort, is a species of carnivorous plant belonging to the genus Pinguicula. It is native to the southeastern United States. The typical variety forms a white flower in blooming. Like other butterworts, it has sticky adhesive leaves that attract, capture and digest arthropod prey to supply the plant with nutrients, such as nitrogen, not found in the nutrient-poor, acidic soil that it grows in. Its name derives from the fact it is usually the first one to flower in the spring.
