    Tim,

    Unlike many plants, you can't just take a part of the meristem (growing tip) of a Nepenthes, sterilize it and put it into tissue culture. Nepenthes are so heavily internally contaminated with fungi and bacteria that meristem tissue just isn't clean enough and the cultures nearly always contaminate. If too little tissue is taken it tends to just form a callus and is difficult to get to grow properly. Meristem tissue is generally regarded as the tissue of choice for putting plants into in-vitro or sterile culture since it is the growing point of the plant and is usually less contaminated with endogenous organisms. Lateral buds have been tried and even the tips of tendils. It can be done but is very difficult and many plants are likely to die in the attempt. So, for a rare and valuable plant, it is a frightening thing to try!

    I believe that all Nepenthes in sterile culture are put in from the seeds, which are reasonably easy to sterilize and then germinate in sterile (or 'in-vitro' ) conditions. The problem is that with many Nepenthes species, the color varies from individual to individual and you never know what you are going to get. With slow growing species it takes about 3-4 years from sterilizing the seeds to finding out what color the resulting plant is. This is why we have put huge effort and very many $$$ into putting as many seeds into sterile culture as possible, For example with N. rafflesiana we have over 300 individuals in sterile culture and are only now selecting for color and form. We'll probably end up with less than 20 which are commercially interesting. We put in over 300 individuals of N. ampullaria too and what did we get - green and speckled! The red forms came from the excess seed that we sowed in the nurseries. Just bad luck but it does limit supply and keep it rare which is kinda nice.

    There's a long answer to a simple question!

    Osmacote: None of the nursery grown plants I show photos of have ever seen an insect or been foliar fed. Only Osmacote. Sure works for us!

    Nathan, it has to be the 'Williams' red'. The pitcher coloration is so much richer than any red N. ampullaria I have ever seen. I hope one day to post a photo of a carpet of ground pitchers. Hope no-one mistakes them for toadstools! [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] No, surely no-one would be that stupid!

    The osmacote trick? Are you talking about putting six or so pellets on the soil surface and watering from above and that is sufficient to get good growth from a Nepenthes?

    So the mass produced plants like xJudithwhatever and ventricosa are started as seed in vitro, then the resulting mass of cells are kept at a certain stage of development where thousands of plants are produced from this one seed?

    It would seem there would have to be some sort of genetic continuity.

    Basically that is how it works Tim. Labs are not limited to keeping just a single culture though. They may have produced cultures from more than one seed. In some cases they are all kept seperate and in others they may be one big mixxed up jumble.

    Is that a Nepenthes in your pocket or you just happy to see me?

    Very interesting discussion. A good read. [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    What IS the osmocote trick?

    I'll answer that question and Joe's as I've done it for several months now. Through capillary action, you wouldn't need to water from the top for them to give off nutrients, it'll get down there. The other way would be to put them a little under the soil, but away from the plant.

    Osmacote and the many new competators have a slow release mechanism, so they are very unlikely to burn the roots of CPs. As Rob has said, in the different mixtures it's possible that say, the Nitrogen is in a different little pellet than, say the Potasium, but if you add six or 8 (in a six inch pot) then statistically you are likely to get at least a little of everything.

    Rob,

    What ever happened to that one Amp with the malformed peristome? Did it start making regular pitchers, or does it still have that wavy peristome?
