Nepenthes are tropical pitcher plants native to parts of South East Asia, India, Madagascar and Australia. Most are vines, but some remain compact in habit. The name "Monkey Cups" comes from monkeys occasionally drinking the fluid in the pitchers.
Hardy carnivorous plants thrive in warm conditions with plenty of bright light in spring and summer, so grow them on a sunny windowsill, in a conservatory or on a sunny patio.
Most carnivorous plants are temperate as opposed to tropical plants, so need a cool spot in winter in order to rest – otherwise they will become exhausted and die. As they go dormant, some plants may die back (and the traps on a Venus fly trap may turn black and die). Place in a cool, unheated room or cool greenhouse – around 7°C is ideal – and keep the compost just moist.
