A slender pitcher plant of northern Sumatra, very abundant around Lake Toba, growing mostly at 380–1800 m. It grows on the ground at forest edges and in open, disturbed scrub with Leptospermum and Rhodomyrtus, often exposed to sun. It is an adaptable intermediate species that does well with moderate nights, bright light and high humidity.

Where it grows wild

Forest edges and open scrub, often with Leptospermum and Rhodomyrtus, usually terrestrial in exposed places and sometimes on rocks. At a peat swamp near Lake Kerinci (about 1100 m) it grows in stunted, dense Rhododendron and Melastoma scrub rarely over 3 m tall. It hybridises naturally with five other Nepenthes species.

Usually 380–1800 m, with some sources giving up to 2750 m. The main measured sites are at about 530–1250 m; one is near sea level.
