About Nepenthes copelandii

Nepenthes copelandii · also called Copeland's Pitcher Plant, Mindanao Pitcher Plant · tropical

Copeland's Pitcher Plant is a tropical Nepenthes endemic to Mindanao in the Philippines, growing on Mount Apo and nearby peaks. An intermediate-to-highland species, it produces slender, often red-flecked pitchers and tolerates a wider warmth range than strict lowlanders. It needs bright humid conditions, mineral-free water and an open carnivorous mix, climbing by leaf tendrils.

Preferred mix: Open, airy epiphytic carnivorous mix

Watch for — Waterlogged roots: Dense, soggy media causes rot; keep the mix open and water by drenching and draining rather than standing it in water.
