    I don't know if anybody else here has had trouble with Pinguicula propagation on the standard peat/perlite mix, but I have. For one, it seems the plants never develop large root systems on peat, but I have also found that cuttings often rot before growing up, or else they quit growing once they reach a certain size. I knew something was wrong, when the only cutting in a batch of p. zecheri on peat/perlite that survived was a stray that had gotten caught on the side.

    So, I tried something different. Last fall, I received a plant of P. agnata x moranensis var. caudata. I dissected the plant into individual leaves, and laid them on rubber foam in a small tupperware container. Here is what they looked like after a few months:

    At that time, the plants had sent roots clear through the ~3/8" foam. I split them up and put all the big specimens in baby food jars with lids designed for tissue culture. This photo was taken a few weeks ago:

    The plants are now filling the jars so I won't be able to get them out without damaging the plants. They have built root systems through the 1" of foam they are in.

    I don't have a lot of species to experiment with, but I have tried and had success with the following:

    P. rotundiflora
    P. moranensis
    P. x " 'John Rizzi' "
    P. x ?

    If anyone else is willing to experiment as well, please do so and let me know how things turn out. Cuttings need to be placed on top of a layer of foam which is sitting in water. If you transplant, cut slits in the foam and insert the plantlets. You also may need to do this if planlets from cuttings don't manage to "catch on" to the foam.

    P.S. The foam used in this experiment is the kind that egg-crate mattresses are composed of.

    Looks pretty successful, and I have tons of that foam.

    But once it roots and matures can you separate it? Or do you tear up the roots trying?

    Hmm, seems like a pretty clean way to do Pings... I'll have to give that a try once I have some cutting material. Has anyone tried this kind of method with rockwool or porous rock as the medium? It seems like the porosity and wicking ability would be key to success. Or, is there something special about foam rubber that makes this work?
    Thanks for the tip,

    I don't know if it has been tried with porous rock or rock wool. The only problem I could see is that the roots might have trouble penetrating penetrating it.

    Once the plants mature, you can cut out the pieces of foam they are growing in and insert them either into larger pieces of foam or maybe into soil media. I'll have to look into that.

    I can certainly appreciate the creativity of it and have plenty of foam rubber at the lab.

    How do you go about doing this without damaging the leaves? I have been toying with taking one of my P. primuliflora apart and laying the leaves on live sphagnum moss (perhaps that would also work in keeping mold away?), but I don't want to bruise the leaves as i do it.

    With P. primuliflora, it's best to just let them reproduce, via the plantlets. Unlike starting things from seed, the plantlets become adult plants in a relatively short amountr of time.

    Where do you get foam rubber?
