  1. LED lighting advice please

    Interesting thread, I was looking into Led light as additional winter lights in my greenhouse for pygmy sundews and mexican pings to help them survive our dark dutch winters. Maybe the following link maybe useful to some of you as well: Verzonden vanaf mijn iPhone met Tapatalk
  2. Thanks for sharing Hannah, and a great new location for your collection Mike, the plants are excellent! Hope to be able to come over next year. Verzonden vanaf mijn iPhone met Tapatalk
  3. Drosera binata 'T Form'

    This clone comes from Sean Spence. Maybe good to correct my previous post here: he still sends plant material to the EU, we had contact after my post. Verzonden vanaf mijn iPhone met Tapatalk
  4. Drosera binata 'T Form'

    As promised some pictures from the "T form" clones I have: Otaki forks (New Zealand): This form occasionally has a leaf with 3 points. Coles Bay, Tasmania: Grampians, Victoria (clone 1): Grampians, Victoria, pale green form: Lake Burbury, Tasmania: Tonimbuck, Victoria: Some damage here from a late cold spell we had last month.. Group shot: The last two clones are still small as I don't have them that long. Beside these clones I also have some clones from the regions Sean mentioned which form also leaves with 4 points. Some of these are as compact as the T-form clones. Verzonden vanaf mijn iPhone met Tapatalk
  5. For psittacina it is quite normal to get a lot of side shoots over time. So I think it is just a sign this is a well developed plant which may need division. Verzonden vanaf mijn iPhone met Tapatalk
  6. Carniflora visit 2017

    As Marcel stated "members of sister societies and forums" are invited as well, so no problem. Verzonden vanaf mijn iPhone met Tapatalk
  7. Pigmy sundews question

    Most pygmies do not set seed very easily without help and I suspect most hybrids may be sterile. Exceptions are D. pulchella and D. ericksoniae (I think that name is outdated now, can't remember what it is now), which are easier in setting seeds. Maybe there are more species, but those two are the ones that I can think of. Verzonden vanaf mijn iPhone met Tapatalk
  8. It is speculation, but it could be caused by difference in growing conditions. If plants have to adapt to much colder conditions (or vice versa), that could make them more vulnerable for fungus attacks. In my experience, some species are attacked more easily then others: rubra for example is more susceptible then most other species. But in general, I don't have many problems either. Have you already contacted Gert about this? Verzonden vanaf mijn iPhone met Tapatalk
  9. My New greenhouse!!

    Very nice, what is the manufacturer? And I assume you chose the polycarbonate cover because of the cold winters in your country? Verzonden vanaf mijn iPhone met Tapatalk
  10. Drosera binata 'T Form'

    I have a nice collection of clones from these regions, partly obtained from you in 2010. As I understood from another collector here in EU, you're not shipping plants any longer to EU? I think in general there are not many around collecting many different binata clones. I hope to find time to post pictures of the "T-form" clones. There are some differences in size and colour.

  11. Hello from Germany

    Welcome! Just can't resist to ask: are you by any chance the Helmut from Sarracenia 'Helmut's delight'? Verzonden vanaf mijn iPhone met Tapatalk
  12. What's this exciting little flower in my pot?

    That depends a bit on what you grow and what you want. If you don't want it spreading to every pot in your collection, you will have to do some weeding now and then. It is more annoying if you grow other Utricularia species or pygmy Drosera then, for example, Sarracenia. If you remove the scapes that finished flowering, you prevent the seeds from spreading. That will help a lot. Verzonden vanaf mijn iPad met Tapatalk
  13. What's this exciting little flower in my pot?

    Well, it is a Utricularia, probably U. subulata, which can spread like a weed. Looks like the flower is not yet fully open or it is a cleistogamous flower, which can occur in this species. If the scapes with more than one flower have a 'zigzag' appearance, then it is subulata almost certainly. Verzonden vanaf mijn iPad met Tapatalk
  14. Drosera Capensis varieties and differences....

    Yes, for the crested variety this might be a mutation only present in parts of the plant. It could be caused by in-vitro propagation. In that case, it could also be a epigenetic thing, that means that it is caused by a change in the way the DNA is transcribed and not by a change in the DNA itself. This will become a bit technical for most of you, bottom line is that it is possible that the crested mutation is not inherited by seed to the next generation, but there is also a chance that it will be. So that will be nice to test. Typical for epigenetic traits is that they sometimes can appear or disappear with different circumstances (stress factors for example). That seems to be the case if I read your observations. Other examples of in-vitro triggered mutations (very likely at least) you can see in all the weird Dionaea mutants in cultivation.

  15. Drosera Capensis varieties and differences....

    Interesting! Do you know if these varieties are stable when grown from selfed plants? Maybe difficult when you grow so many varieties side by side (hard to exclude hybridization), but maybe you tried this? Verzonden vanaf mijn iPad met Tapatalk
