About Pinguicula L.
Pinguicula lutea, commonly known as the yellow butterwort, is a species of warm-temperate carnivorous plant in the family Lentibulariaceae. It grows in savannas and sandy bog areas of the Southeastern United States. The flowers of Pinguicula lutea are usually bright yellow or straw-yellow, and white-flowered specimens are very rare. Like all insectivorous plants in the genus Pinguicula, P. lutea traps small insects using specialized glands on the surface of its basal rosette leaves. Pinguicula lutea occurs along the Gulf Coastal plain of the southeast USA. It is commonly found in Alabama, Georgia, Mississippi, North Carolina, South Carolina, Florida, and southeast Louisiana. Compared to other Pinguicula species native to the South, Pinguicula lutea thrives in a drier environment. It prefers to grow on nutrient-poor soil in acidic bogs with a pH ranging from 5.0 to 6.0. The soil it grows in is typically a 50:50 mix of peat moss and sand. P. lutea favors partially shaded areas such as open pine woods, marshes, moist savannas, and sandy soils.
