WHAT ARE PINGUICULAS?
Pinguicula grow throughout much of the Northern Hemisphere, from the Arctic Circle down through Europe, Siberia, and North America. Many spectacular forms exist in Mexico. South America also has a few species. Pinguicula are typically small plants which grow in a rosette fashion. The leaves of pings have tiny transparent hairs which secret a sticky glue. There are also sessile glands on the leaf which are dry, until an insect is captured. When an insect is caught the sessile glands secret acids and enzymes which start to dissolve the insect. Then the sessile glands reabsorb the nutrient rich fluid.
