Nepenthes, or tropical pitcher plants, are carnivorous, trailing vines (170+ species) that thrive in warm, high-humidity environments (60%+), using specialized, nectar-laced, pitcher-shaped leaves to trap and digest insects. Ideal care requires bright, filtered light, well-draining, nutrient-poor substrate (e.g., sphagnum/perlite), and consistent moisture using rainwater or distilled water.
