Pinguicula: The Butterworts

 This genus contains approximately 70 species. A few species of Butterworts are indigenous to South America, but the majority of are found in the Northern Hemisphere. Mexico is home to the most diverse selection of  Pinguicula species.
     In the wild, Butterworts are indigenous to a variety of climatic zones, from the extreme cold of the Arctic circle to the hot, humid Caribbean tropics. The habitat of Pinguicula is equally diverse, as Butterworts can be found in the wet, peaty bogs of northern Canada as well as the hot, dry calcareous cliffs of southern Mexico. It is important to consider the original habitat when cultivating Butterworts in order to select the correct potting media and growing conditions for the various species.
     Although Butterworts do not display the intense foliage colouration exhibited by other carnivorous plant genera, Pinguicula more than makes up for this by producing some of the most vibrant, striking flowers of the carnivorous plant world.
