Nepenthes are tropical pitcher plants that need very different growing conditions that other carnivorous plants. They should be planted in well-draining potting mix that is not too high in nutrients, and most need at least four hours of bright sunlight per day.
"Highland" Nepenthes tolerate the temperatures and humidity levels typical of most homes, but are healthier with lower evening temperatures (45-65 F or 7-18 C).
"Lowland" species often require higher humidity and evening temperatures (70F or 21 C and up). But great choices for home growers are hybrid Nepenthes that grow vigorously in typical household temperatures.
