The majority of Nepenthes species
are indigenous to southeast Asia, although their range extends from northeastern
Australia to northern India. The island of Borneo is particularly rich in
In their native habitat, Nepenthes are found at a variety
of altitudes, from sea level up to an altitude of 3000 meters
(10,000 ft) depending upon the species. In the tropics, the
climate can change dramatically as the elevation increases.
Plants adapt to these climatic zones, and become somewhat
intolerant of environmental conditions differing from the climate
of their indigenous region. When cultivating Nepenthes, it's
necessary to mimic the native environment of each species as
closely as possible, in order to maintain the health and appearance
of the plant. Nepenthes species are classified as Lowland and
Highland; these categories indicate the approximate elevation
where the species normally occurs.
