This classic lowland species found across Borneo, Sumatra and Peninsular Malaysia. The upper pitchers are very different in form from the lowers, and within the species itself, there is a great deal of variability in the size, morphology and colouration of pitchers, even across individuals within the same colony of plants. It hybridises regularly in habitat with nearby species, including N. gracilis, N. ampullaria, N. bicalcarata and various forms of N. mirabilis, to name but a few. In any colony of Nepenthes rafflesiana, it’s common to find hybrids, unless it’s very geographically isolated from other species. Therefore, it’s unlikely that there is any such thing as “pure” Nepenthes rafflesiana, which may explain the wide range of variability observed in habitat.
History: First introduced in 2008.
Climate: Lowland. We find it grows best between about 32 deg. C (90 deg. F) in the daytime, down to 24 deg. C (75 deg. F) at night, although it will tolerate temperatures outside this range.
