  1. More fantastic photos! :D

    After viewing Siggi Hartmeyer's excellent "Snap Tentacles and Runway Lights" DVD, I pay much more attention to the Snap Tentacles, looking for them on all Drosera plants I inspect, and like Christian said, I notice your D.rotundifolia appears to have snap tentacles! I didn't realise this species had them - is it a special form of the species, or maybe a hybrid? Has anyone else noticed snap tentacles on any of the European Sundews (D.anglica, D.intermedia & D.rotundifolia) ??

  2. Perhaps there are slug-repelling chemicals in the Droseraceae... I've noticed slug/snail trails over pots of various Drosera species in the past (pygmys, D.capensis, rosetted S.African species, D.binata, .... etc), but I never seem to recall seeing any actual mollusc-related damage - very strange! Would be interesting to test out this theory (anyone want to send me a spare D.meristocaulis or D.hirticalyx to test it out on ??!! :lol: )....

  3. Hi Siggi,

    I think you misundertood - I've already received the DVD (2 days ago now - I ordered it on Friday 12 May 2006, and it arrived the following Wednesday, 17 May 2006 - how's that for service!), and it is indeed excellent! I recommend it to all keen Drosera enthusiasts! :lol:

  4. Well, to post a follow-up:

    I received my DVD in the post from Siggi yesterday morning, and have watched the DVD twice since then!

    To reiterate what Vic has already said: it is an excellent DVD, highly recommended for CP enthusiasts (and especially Drosera enthusiasts).

    There is also a "taster" at the end showing a few minutes of clips from another of Siggi's DVDs, about Borneo Exotics in Sri Lanka.

    Based on this, I may get some of the other "Hunting Veggies" series DVDs.

  5. Hi,

    I'm just wondering if Pinguicula moranensis 'Libelulita' is in cultivation anywhere within the EU? I just did a quick forum search, with no results.

    I've just been leafing through some old copies of CPN (Carnivorous Plant Newsletter, the excellent quarterly journal produced by the ICPS [international Carnivorous Plant Society]), and read the cultivar description in CPN Volume 31 No 3 (September 2002), with a great photo of it on the back cover.

    It looks like a stunning cultivar.

    Anyone in Europe grow this? Is it available this side of the pond?! :shock:

  6. Hi Greg + Jim,

    Well I've has some success in using the leaves from the succulent winter rosettes: gently pull of some of the outermost leaves, including the base of the leaf, then gently lay them on some damp potting mix, and keep them just slighly damp, cool (but frost-free), and out of direct sunlight, NOT in stagnant conditions but with good air circulation (a greenhouse or windowsill is ok), and they seem to form buds at the leaf stem bases within a few weeks. As for potting mix: I've used the same that I use for adult plants (2 parts Seramis [clay granules], 2 parts Perlite, 2 parts Vermiculite, 1 part Silver [silica] Sand, 1 part John Innes No. 2 [Loam]), and that has worked ok. I've even just layed the cuttings on the surface of the same pot that the parent plant is in, and they have formed buds. You could also try a cutting mix of equal parts Perlite and Vermiculite, kept just barely damp. Other people have had good results laying the cuttings on damp sphagnum. I'm going to experiment myself with different techniques, to see which give the best results.

    I think the key points are:

    - Use an "open" well-drained potting mix

    - Use outermost leaves from the succulent winter rosette where possible

    - Use the entire leaf (new buds usually arise from the stem bases, where the leaf attached to the parent rosette)

    - Keep the soil just damp, not too wet

    - Not too much humidity (just average)

    - Keep the cuttings in good light, but out of direct sun (a North facing windowsill [or South facing in the Southern Hemisphere] may be a good idea)

    - Don't keep them in "stagnant" conditions: good air circulation (i.e. normal room or greenhouse conditions, not terrarium) may help

    - Best time to take: many people say just when the new carnivirous leaves are starting to appear from the centre of the rosette in spring or early summer, but probably anytime after mid-winter is ok

    These are just some of my own ideas / opinions - please feel free to correct if you think I've made any errors! :D

    I'm not sure how easy it is to take cuttings from some of the species that form "underground bulbs", e.g. P. heterophylla, P. macrophylla, etc: I guess you would have to unpot the plant, and carefully "peel away" a few outer leaves from the hibernaculum. Maybe someone else can comment on these?

    Anyway, I hope this provides at least some ideas on the topic!

  7. Thanks Aidan, that exactly what I meant! Many Drosera "named varieties" in particular seem to "breed true" from seed: for example, D. capensis variants ('Albino', 'Red Form', etc), even other "named forms" of D.filiformis var filiformis (e.g. 'All Red [no dormancy]') seem to come true from seed. Which is why I was wondering about D. filiformis var filiformis 'Florida Giant'. Maybe this was introduced into cultivation via seed from a population of extra large plants? (This variant seems twice the size in all parts [including the flowers] to the "regular" form). On the other hand, if it was introduced via a leaf cutting taken from an individual extra large plant growing amongst a "normal" population, then I would expect that indeed it may need to be reproduced via vegetative means only.

  8. Thanks for the kind comments - they were only hasty snapshots, so some aren't of the best quality!

    @Gawd: well, my label for the hybrid states:

    P. agnata x moranensis x ehlersiae

    (of course, that could be either one of:

    P. agnata x (moranensis x ehlersiae)

    P. (agnata x moranensis) x ehlersiae

    P. (agnata x ehlersiae) x moranensis

    I have no idea which - could even be altogether incorrect!)

    I was just wondering if this was a well-known hybrid that anyone recognised, and if so if it was correctly ID'd! I obtained the plant from Phil Adedeji - haven't heard from him on the forums for a while.

    @Aidan: please do post some pics anyway, yours are always superb quality! (No pressure there then... :lol: )

    I just love the show that Pinguiculas put on in the winter (and indeed all year round): I reckon 2006 will be "Year of the Ping" for me! :tu:
