Nepenthes are tropical pitcher plants found predominantly in Southeast Asia. Species can be found from the steamest lowland jungles to the most frigid tropical mountaintops which see frost on a regular basis. See our Nepenthes care guide for general cultivation information. Though many species are much more tolerant of temperatures than their natural range would suggest, this guide provides a good starting point for learning about the cultivational temperature requirements of many species. We often find that Nepenthes crosses provide a great deal of hybrid vigor for size, growth and hardiness. Here's our sizing guide for a description of plant sizes for Nepenthes.
