Nepenthes, known as Asian pitcher plants are a group of carnivorous plants. They are roughly 140 natural species and many more cultivated hybrids.Many come from lowlands, humid and hot weather. They live in hot days but cool or cold night. A few are consider tropical alpines and can tolerate near  freezing temperatures.The environment to grow them is similar to orchid cultivation. I’m trying 10 different hybrid cultivars in my glasshouse.
