Pinguicula esseriana is a carnivorous plant from the butterwort plant family (Lentibulariaceae). It originates from the northern part of Mexico and reaches a maximum diameter of 2 cm. The plant produces a rosette of egg-shaped to oval, purple-green leaves. The upper side of the leaves is covered with many glands producing a sticky substance where insects could be caught with. The insects are digested on top of the leaves, the nutrients available are used by the plant. In high light conditions, it is possible for the leaves to turn a brighter red to purple. Once per year, mostly in spring, one to several flower stalks are produced carrying a single faint-purple, spurred flower. Flowers are somewhat similar to the flower of a violet. Propagation is done by repotting the smaller rosettes forming near the base of the mature plant, or seeds.

For optimal growth of Pinguicula esseriana, provide temperatures between 15 and 25 degrees Celsius from spring to autumn. Most commonly in this season it produces carnivorous leaves, and it is actively growing. Provide a lot of moisture, and a humidity of at least 70 %. In winter this plant could handle colder temperatures. The plant is most likely producing non-carnivorous leaves and could be kept dry in between waterings. Ensure optimal ventilation at all times. This species is mostly grown in bright rooms indoors, cool greenhouses or specialized terraria. Pinguicula esseriana grows best with bright indirect light. Direct sunlight could scorch the leaves. Pot this plant in mineral rich soil that is able to maintain moisture. Make sure that this soil contains very little nutrients. Fertilizer is rarely applied; it is possible to ‘feed’ the leaves with small insects occasionally.
