Seed - Nepenthes robcantleyi Q x edwardsiana Wide Peristome 10-2026

The mother plant is Nepenthes robcantleyi Q, a female clone from my own collection. Named for Rob Cantley and described in 2011, this Philippine species is known for massive, dark pitchers and a thick, rolled peristome, and wild populations are limited to a very small area of Mindanao.

The pollen parent is edwardsiana Wide Peristome. Found on Mount Kinabalu and Mount Tambuyukon in Sabah, edwardsiana grows in ultra highland conditions and produces tall, narrow upper pitchers topped with one of the most elaborate peristomes in the genus. This clone was selected for an especially broad peristome, with tall ribs flaring out into a wide, ruffled collar.

This cross pairs robcantleyi's size, dark color, and heavy peristome with a wide peristome edwardsiana, so both parents are pushing in the same direction. The robcantleyi side should also make these seedlings more adaptable than pure edwardsiana, which can be famously fussy in cultivation.

Each pack contains approximately 30 seeds, harvested October 2026.
