Pinguicula esseriana
Pinguicula esseriana is a species of carnivorous plant. This species is a tropical variety and is native to the gypsum cliffs and mountains of Northern Mexico. This species rarely exceeds one inch in diameter when fully grown and produces small broad leaves with upturned edges during warm months. In winter the leaves lose their sticky surface. P. esseriana is most often grown for its flowers which are light pink to purple and are produced by vigorous plants from early spring to mid to late summer (D'Amato, P.).

This species of carnivorous plant uses sticky secretions on the end of small hairs to trap insects, usually gnats and midges. Once stuck to the leaves, insects are slowly decomposed by enzymes secreted by the leaf glands.

In cultivation, P. esseriana prefers a potting mix of equal parts sand, perlite, vermiculite, and peat. Gypsum may also be added but is not considered necessary. Plants should be watered overhead during the summer and kept damp but not wet. Unlike many other carnivorous plants, P. esseriana is not a bog species. This species is also tolerant of light frost but should be protected from very cold wind and temperatures below 40°F if possible (D'Amato, P.).
