Nepenthes ‘Dark Secret’ – Cultivar with Near-Black Pitchers


Nepenthes ‘Dark Secret’ is a dramatic cultivar introduced through the Borneo Exotics breeding program. While its exact lineage has not been published, growers note a strong influence from N. ampullaria. At first glance, young pitchers may resemble those of N. ‘Lady Luck’, but as they mature they darken significantly, often developing peristomes that are nearly jet black. This intense coloration makes it one of the most striking Nepenthes hybrids in circulation.
