Nepenthes rigidifolia is a critically endangered climbing pitcher plant from Sumatra, found at 1,000 to 1,600 m in lower montane forest. It is a wild species, with very few plants remaining in the wild, so it is not a common garden plant; grow only from legally sourced cultivated stock, and keep it humid and bright.
Nepenthes rigidifolia is a critically endangered tropical pitcher plant endemic to Sumatra, where it grows at elevations of 1,000–1,600 m above sea level.
The specific epithet rigidifolia is formed from the Latin words rigidus (rigid) and folia (leaves), and refers to the plant's stiff, coriaceous leaf blades. Tahul-tahul has been recorded as a local vernacular name for this species.
Nepenthes rigidifolia is endemic to Sumatra, where it has been recorded from a single small area near Sidikalang in Karo Regency, North Sumatra province. The only known population of this species grows on a road bank. The describing authors counted 24 mature plants at the type locality. Subsequent field observations suggest that the population has since dwindled in number, with perhaps only two plants remaining. Nepenthes rigidifolia grows terrestrially in lower montane forest and scrub. Young plants have been observed growing as lithophytes. The species has an altitudinal distribution of 1,000–1,600 m above sea level. It grows sympatrically with N. spectabilis and a natural hybrid between these species has been recorded.
