There are several societies around the globe where enthusiasts of carnivorous plants joined together to share their experiences with carnivorous plants. Often there exists a society newsletter with articles about different species, field trips or local activities.
In Germany the Gesellschaft für Fleischfressende Pflanzen (G.F.P.) is a carnivorous plant society founded in 1984 by a group of CP growers. Today there are more than 800 members not only from German speaking countries. 2 to 3 times a year a society's newsletter is published under the name "Das Taublatt". There is an annual meeting of the society members with a plant sale.
A more international society dedicated to carnivorous plants is the International Carnivorous Plant Society located in the USA. Its publication is named "Carnivorous Plant Newsletter" where you can find more scientific articles concerning CP's.
