  1. Yes. Indeed, I can even send you this very same plant (just not in flower anymore). Let's talk by PM.

    Utricularia subulata

    More favourable conditions (strong light, grown alone or at least with enough space, etc.) induce chasmogamous vs. cleistogamous flowers. Interestingly, I get chasmogamous flowers preferably in winter (indoor setup), and cleistogamous ones year round.
  3. Something people from the East coast of North America probably see frequently, but for me it is very exciting to induce Utricularia inflata flowering at home, after a few years growing it (container with clean water obviously just for the photo). It is a very elegant plant, the peduncle ca. 15-20 cm long, and can get much longer. And the flowers are nicely scented.
  4. Maybe you put too much emphasis on the algal/moss development to decide whether a substrate is of good quality or not. I think the key question would be: what is special in your new peat that does not allow algae/mosses to grow? I have got moss growth even in sterilized peat given enough time (so spores can reach the place) and favourable conditions for its development. If I get a peat that is not colonized by mosses at all (in places where moss is favored to grow), I would be suspicious...
  5. The definition of a cultivar is "an assemblage of plants that (a) has been selected for a particular character or combination of characters, (b) is distinct, uniform, and stable in these characters, and (c) when propagated by appropriate means, retains those characters". Also, in considering whether two or more plants belong to the same or different cultivars, their origins are irrelevant. For example, if a group of plants (not only one) is registered as a cultivar because of a certain set of traits, descendants by sexual reproduction also retaining those traits may form part of the culti
  6. Hi! Do you mean U. biloba? I grew it for a while, and even got it flower, but I lost it during one vacation period. I do have U. subulata. It is difficult to kill, hehe.
  7. Thank you very much for your answers, ada! Yes, it is very frustrating sometimes. Nigel, your webpage looks particularly nice and by no means I was referring to you with my message (I have not ordered yet plants from you, so obviously I cannot provide any opinion). But there was no confusion, I was talking about professional sellers, not just people who had a few extra plants and sell them from time to time. I may order something next season if I can get some more space, hehe, for instance to broaden my Sarracenia purpurea collection. By the way, the S. purpurea subsp. venosa you offer in
  8. Hi! I am trying to broaden my Utricularia collection and I have found that missidentifications are not that unusual, so I wanted to ask, in general, what do you think that can be done when a seller is offering a plant which is missidentified. I am talking mainly about professional sellers and "normal" orders (something offered with a price and you order it), not amateurs or exchanges. I guess that, if a professional is selling a product, they should have some responsibility about its identity, don't you think so? The problem is that, in some cases, to properly identify a plant i

    So you are clearly using Sphagnum as potting media! This last one is linked with Sphagnum. It looks like the very common Galerina paludosa, although there are some species (and even different genera) of Fungi growing on Sphagnum and developing fruitbodies with a close appearance.

    Nice specimens. It is for sure a Leucocoprinus. I do not see the colour of the scales very accurately, and Leucocoprinus species are often difficult to distinguish, but if the scales are definitely lilac-purplish it may be L. ianthinus/L. lilacinogranulosus (depending if you consider them as different species or not).

    My Sphagnum

    Now, it is!! Congratulations The details are magnificient to show the differences. I have also found it in my pots, I send another comparison of a species that probably belongs to S. sect. Sphagnum and S. squarrosum. Such a lovely genus.
  12. I am not sure if I am still in time to participate, but I will bid £5.
  13. I agree with Karsty, though the exact composition of slate is somewhat variable. Keep an eye on the terrarium to see if the plants like it. Regarding the vinegar proof, it only serves as an orientation of the presence of a limited number of carbonates, mainly sodium and potasium carbonates, but those are very soluble and normally not present in many rocks. With the common calcium carbonate it will work if the solution is not too cold and if the rock contains not many impurities. But you may have, for instance, magnesite (magnesium carbonate) and even dolomite (magnesium and calcium carbon
  14. Thanks! And no, they have stalked glands, or glanduliferous trichomes, as you prefer :-)
