Also commonly known as tropical pitcher plants and Nepenthes, this plant comes from a family of more than 120 species. Monkey cups are vine-forming that can be found in its natural habitat in the tropical region of Asia, mainly Philippines, Malaysia, Thailand, Indonesia, Singapore and New Guinea.
The plant grows as a climbing vine and its name comes from monkeys occasionally drinking the fluid found in the pitchers, which are actually a swelling of the mid-vein in the leaf. Due to nectar secretions and colouration of the pitchers, insects are attracted to them. In fact, once an insect fell into the pitcher, it will be digested by the fluid at the bottom of the trap.
