These started in test tubes I ordered on eBay. They have been extremely easy to grow.
They are named after Joseph Dalton Hooker who discovered them. The first mention of them seems to be around 1848
Originally thought to be a species they are a natural hybrid between N. ampullaria and N. rafflesiana. They are found deeper in the jungles climbing up the trees. Early descriptions disagree on everything from the leaves to the pitchers to the growth habit. The wings and roundness of the pitcher seem to be all anyone agreed about.
I haven’t seen upper pitchers on mine yet, but read that they are longer and without wings.
Common to lowlands of Borneo, Malaysia, Sumatra where they grow in bogs.
High humidity, 60’F-90’F, easier to pitcher than some other Neps. I find they do best in open orchid baskets filled with sphagnum which are placed in a dish in which I maintain 1/2″-1″ of distilled water.
