  1. Hi Eric, you make a good point about the other pigments that can be present. It may be that the very light vein colour that occasionally occurs is not Anthocyanin but something else entirely, and only manifests during stress conditions. It would be interesting to see some talc results on it versus normal anthocyanin red. Best regards chris
  2. Yes Charlie, there seem to be several levels of effect and possibly also where they are affected. The stress may be due to complex epigenetics, not only what genes are there but which are switched on. Very interesting stuff. best regards chris
  3. Yes Eric, your stressed pitcher looks very similar, I note no red around the dying back bits, yet faint red veins visible. I have not seen this in my purp heterophylla (yet). The question of how many sections of the process could be affected is interesting, yellow flowered forms with normal pitcher colour may be an example of this I suppose. I think it was Carl Mazur who recorded the circles of veinless round af plants, perhaps they are not related, other than they are both clearly ‘not normal’. The suffused pink of plants like Melissa Mazur, st least in my plant seems another different expression of pigmentation, and reverse veining yet another. I am not sure how well these reproduce of selfies. brst tegards chris
  4. Not sure if this image is any better
  5. Yes Ada, they are a wonderful set of plants, often very vibrant and eye catching. The interesting thing is that they seem to be able to take full sun, not what one would expect from a plant lacking pigment. best regards chris
  6. Hello Eric, thank you for the comprehensive reply, I am away at the moment but will try better pictures when I return, however the level of pigment is very low, yet clearly present, only seen in the veins. The suggestion that an external factor can turn a bit of the leuco precursor red makes sense, so this would not be due to a leaky gene, just to chemistry I guess. It came as a surprise as I have never seen it before. I raised the veinless idea simply because the bits written about them in situ suggested these population rings surrounding the heterophylla plants, though none of my crosses with af and normal plants have yet yielded veinless. Are you able to receive plants from the uk, I would be happy to send one of each cross. best regards chris
  7. Thanks Ada, I have yuor cross but not noticed it having any red yet. This is really interesting, I am now wondering how veinless plants fit into this and especially how the wild populations with rings of veinless around af plants works, quite leaky genes?, very lesky genes?? chris
  8. Thanks Alexis, interesting possibilites. I have never noticed this until recently, and only with purp heterophylla crosses, all other af seem 'clean' of colour. chris
  9. Thanks Ada, leaky gene seems to refer to mutations, rather than the recessive genes that have been assumed for many af plants. does that mean that af is not an absolute? I have only observed this with purpurea heterophylla as a parent, do you know it if occurs with crosses of other af crosses that do not include purp heterophylla. furthermore wher do the veinless and almost veinless belong in all this? more questions than answers, perhaps one for some pure research then. best regards chris
  10. I have been observing some interesting traits that occur when hybridising with Sarracenia purpurea ssp purpurea v heterophylla and see some strange and unexpected results. The parent heterophylla is completely green, has no pigment in the growing point, flowers or where damage or die back occur. It is the characteristic yellow/green of what I consider heterophylla should be. The crosses are: S. Purp heterophylla x rubre gulfensis AF And S. ((Leuco AF x rubra jonesii AF) x Suspicion) x purp heterophylla. In each case the other parents look correct for AF, and in each case the offspring look ok for a purpurea cross in shape. They both show no signs of red pigment in the growing point and no red in damaged or die back areas. However, some of the seedlings have developed a very faint red veining in the hood. It is very faint, but clear, apparently like those called semi-veinless. The growing points are free of all red colour, damage and die back is clear of red, only the light veining in the hoods makes these different. All plants are grown in full sun at all times. I can only guess that perhaps: The purpurea is not truly a full heterophylla, if so this may be true of many of the clones in cultivation Or There are some recessive genes that become activated in further crosses Or Some other anomaly is occurring. I have found little or no research on semi-veinless plants, the assumtions from field work seem to be that they are a result of back crosses from AF forms, and yet from my small experience with these crosses I think the possibility that they are an unusual expression of 'not normally visible' genes that only become visible when normal AF is present is a strong possibility. Has anyone else seen this? or researched it? chris Read more: http://sarracenia.proboards.com/thread/4199/anthocyanin-free-semi-veinles-sarracenias#ixzz5RY4KxyHc

    I use ikea white pots with holes drilled in, they seem to be ok, and are cheap. chris

    Sarracenia x willisii anyone

    Hi Alexis, there are (is) one photo on cpphotofinder that looks right perhaps http://cpphotofinder.com/sarracenia-x-willisii-3314.html though I do no know the history of the photo. I am intereted to see if there are others around - and now what of all the mislabelled plants? why do they continue to be mislabelled I am working to make it with purp montana just for the fun of it. best regards chris
  13. This hybrid grex comprised of (purp x psit) x ((purp x flava) x purp) seems to be rare or absent in collections. There is an imposter that has a lot of leuco in it (from long distant discussions with Slack this posssibly came from Australia to Slack and I think it was x willisii x leuco but lost the x leuco part of the label). The imposter is a fine plant, but continues to be mislabelled by even the most careful collectors, including hybrids made from it. Is anyone growing the true x willisii? If so can we please see some photos.... Thanks chris
