Nepenthes Hookeriana grow from seeds Print
Nepenthes × hookeriana,  after Joseph Dalton Hooker), or Hooker's Pitcher-Plant,is a common natural hybrid involving N. rafflesiana and N. ampullaria. It was originally described as a species.
It is a relatively common natural hybrid found in lowland conditions throughout Peninsular Malaysia, Borneo, Singapore and theIndonesian island of Sumatra. Like its parental species, the hybrid is generally found in recently disturbed clearings.

 

 

Grow Nepenthes Hookeriana from seeds

Nepenthes seeds can be started on chopped live sphagnum moss in very damp but not wet conditions. If the sphagnum starts to overgrow the seeds, pinch it back with a forceps. If you use dried long fibered sphagnum instead, you may re-hydrate it with boiling water to reduce contaminants somewhat. If you cook it too much, the moss breaks down and molds very easily when it is eventually contaminated. Another option that works well is to use coir, also called coco peat. Make sure you get a brand that says something like the coir "is exposed to rain water from at least three monsoon seasons" on the label. I especially like coir that has a 50% to 75% content of long fibers. I am not sure it is available any more. An option would be to add washed perlite to the coir.

Sprinkle the seeds onto the surface of the medium, spray with pure water, and place the pots in plastic bags in warm temperatures, about 26°C to 32°C (80°F to 90°F). Plastic bags will keep the humidity high and will exclude fungus gnats and spores of mold and moss. The pots should be in light shade or under fluorescent lights. Germination can take from 4 weeks to almost a year. The fresher the seed, the stronger the seedlings and higher the germination rate.

Keep an eye on the seeds since mold can be a problem. Generally, if the seeds are viable and have been stored well and the medium you use is inert, you will not have problems with mold. If you do see mold, spray the seeds with pure water. It is probably a good idea to do this anyway to encourage germination.

The seedlings can remain in the original pots in plastic bags under lights for one to two years.

 

 If the soil surface gets nasty with cyanobacteria or moss or the small plants are too close together, carefully transplant to new media, in new pots, in new plastic bags, and put them back under the lights.
Something I do is after six months, if the seedlings are not bright green, I put high nitrogen (19-6-12)  pellets about 1 cm into the soil spaced about 2 to 3 cm apart--I put 4 pellets in an 8 cm square pot. The seedlings usually green up nicely and grow like crazy.
When the plants get large enough you can put a piece of dried blood worm (a kind of fish food) into the pitchers. 

 

Only do one or two at first to make sure it works under your conditions.
After about two years the seedlings can be repotted, spaced apart, and put into a terrarium or greenhouse. After they are established in the pots and you can see water in the bottom of the pitcher, and the pitchers are big enough (what is big enough?), you can try putting Osmocote™ pellets into the pitchers. Select the smallest pellets and put one pellet per plant and probably only one plant at first. If nothing bad happens after a few weeks, try a pitcher on other plants.
