Ultra-Highland Nepenthes: Temperature Demands and Coir for Seed Germination

A grower asks about ultra-highland species (N. rajah, aristolochioides, villosa, edwardsiana, macrophylla) and using coir for seed germination. The expert confirms all need days in the 70s°F, nights in the 50s–60s°F with high humidity. N. aristolochioides is easiest; N. edwardsiana is nearly unobtainable and extremely touchy; N. macrophylla is moderately available. All are slow.

Coir for Nepenthes Seeds

Coir works well – soak and rinse thoroughly to remove salts. It's the sole medium used by Sam at Lelani Nursery for Nepenthes germination.
