Pinguicula caerulea

Blue butterwort

A butterwort of the south-eastern US coastal plain, from North Carolina to Florida, with a flat rosette of sticky yellow-green leaves and violet-blue flowers from late winter to spring. It grows in wet, acidic sand in pine savannas, flatwoods, bogs and ditches, and keeps its rosette through the mild winter. It wants a humid, warm summer, a cool but not frozen winter, and constantly moist, lean sand.

Moist sandy pinelands, wet pine flatwoods and savannas, seepage bogs and roadside ditches in the coastal plain and Carolina sandhills, in nutrient-poor, acidic sand. It grows among grasses and sedges under an open pine canopy, often in partial shade.

Coastal plain lowlands, from near sea level to about 150 m.
