BE-4013. Originating from Sultan's Peak in Palawan, this is believed by many to be possibly the largest of all Nepenthes species and has been recorded to capture and consume rodents. This plant forms voluminous and toothy pitchers which dangle from extraordinarily long tendrils. It is highly recommended to grow this species in a large pot of an akadama based mix, in order to support the fine and extensive root system put out by this plant.
