Pinguicula lutea
A butterwort of the southeastern US coastal plain, with a flat rosette of sticky yellow-green leaves and bright yellow flowers on stalks up to about 50 cm tall. It grows in open, fire-maintained wet pine flatwoods and savannas on acid, sandy-peaty soil. It grows through the mild winter and flowers from February to May, and it needs strong light, a lean acid medium and pure water.
Where it grows wild
Open longleaf pine flatwoods, moist savannas, bog edges and disturbed sandy spots such as roadside ditches, on nutrient-poor acid soil with a pH of about 5–6. Regular fires keep the ground open, so the rosettes sit in near-full sun among low grasses and sedges.
Found on the low coastal plain, mostly below about 100 m. Few records carry an elevation, so this was not measured.
