Nepenthes, or the tropical pitcher plant, are once again a passive trap plant, whose traps resemble the shape of an urn or pitcher. The genus is divided into two main groups, highland and lowland Nepenthes. It is home to some of the carnivorous plants' biggest pitchers, and the oldest of Nepenthes plants have been known to have eaten small birds. These are some of the most sought after plants in cultivation and are perhaps some of the most deadly. These plants can grow to be all different sizes and even the pitchers take on different shapes.
