Pinguicula vulgaris

Pinguicula vulgaris, commonly known as the common butterwort, is a graceful carnivorous plant of cool, nutrient-poor wetlands and calcareous bogs across Europe. This perennial species forms a low, flat rosette of smooth, pale green to yellow-green leaves with a slightly greasy appearance. The leaf surface is covered with microscopic glandular hairs that secrete a sticky substance used to trap small insects. Once prey is caught, the leaf margins may gently curl inward, while digestive enzymes break down the insect and release essential nutrients, allowing the plant to survive in soils that are otherwise extremely poor. Pinguicula vulgaris occupies a different ecological niche from sundews. It typically grows in moist but not fully submerged habitats, such as bog margins, wet meadows, springs, and calcareous fens. It tolerates cooler temperatures and seasonal fluctuations in moisture, often experiencing cold winters and short growing seasons. In late spring to early summer, Pinguicula vulgaris produces elegant violet-purple flowers on slender stalks that rise well above the sticky leaves. The plant often retreats into a compact winter bud (hibernaculum).
