Nepenthes edwardsiana
Also called Splendid Pitcher Plant
Nepenthes edwardsiana is a rare, climbing carnivorous pitcher plant from the mountains of Sabah, Borneo, known for some of the largest pitchers in the genus. It is an alpine highland plant that needs cool, humid conditions and very careful growing.
Nepenthes edwardsiana , or the splendid pitcher-plant, is a carnivorous tropical pitcher plant endemic to Mount Kinabalu and neighbouring Mount Tambuyukon in Sabah, Malaysian Borneo. It is considered one of the most spectacular of all Nepenthes, producing some of the largest pitchers and the most highly developed peristome ribs of any species in the genus.
Nepenthes edwardsiana is very rare in cultivation and little information has been published on its growing requirements. Generally speaking, it is an alpine plant that requires highland conditions to grow well.
In 2004, professional horticulturist Robert Sacilotto wrote a summary of measured tolerances of highland Nepenthes species, based on experiments conducted between 1996 and 2001. Out of all of the studied species, N. edwardsiana proved to be the most challenging. Cotyledon-stage seedlings showed a 100% mortality rate when exposed to the following conditions: relative humidity constantly over 90%, water droplets present on the leaves, soil conductivity over 45 microsiemens, and soil pH above 6. However, several plants grew well in a substrate consisting of 50% perlite, 30% Sphagnum moss, 10% peat moss chunks, and 10% fir bark. A top dressing of live Sphagnum was found to provide a good anchoring point for developing roots.
