As with all plants, the key to successfully growing Nepenthes in cultivation is the ability to replicate the conditions of their natural habitat.
Most of the 170+ Nepenthes species are found in Southeast Asia - particularly Borneo, Sumatra, and the Philippines - and the genus ranges from highland montane plants to those inhabiting steamy lowland jungles. But their cross-fertile nature has resulted in countless unique hybrids, both in cultivation and in the wild.
This guide aims to help growers of Nepenthes estimate the requirements of specific plants. It comprises two tools: (1) a calculator which visualises the temperatures likely preferred by a given species or hybrid, and (2) an interactive list of every Nepenthes species, which can be sorted and filtered according to altitude and locale.
Happy growing!
