  1. Thanks for the comments Aidan + Joseph.

    Well, it looks as if Trichoderma is definately the way to go - a nematode and Fusarium fungus deterrant all in one, and a biological one as well! Useful as a preventative at least.

    I'll order some on Tuesday, and hopefully will revisit this topic with my findings in due course.

    Thanks again for all the information and help.

    P.S.: *** HAPPY NEW YEAR! ***

  2. Thanks Aidan - I had completely forgotten about that article!

    It looks as though the only really useful application of a nematicide would be as a temporary preventative measure - for example, if signs of Fusarium infection appear in one plant in a collection, it could be applied throughout the entire collection (along with Trichoderma), to help the infection from spreading further. Now all I'll need to do is trial some nematicides later in spring / summer on some spare plants (I doubt any have been used much on Pinguicula).

    As for saving plants already infected, I guess there are only 2 options: try to take leaf cuttings, using just healthy portions to leaves (usually the tip of the leaf, as Brown Heart Disease spreads from the centre outwards) - making sure no infected portion is used - or following the suggestions in the CPN article you mentioned (i.e. moving infected plants to a shaded, ventilated "quarantine area", keeping them completely dry). Personally, I'm a bit skeptical about the second method, as in my experience Brown Heart Rot spreads so quickly that an infected plant can be dead within a few days of the infection first becoming evident. The CPN article refers to a trial in Australia (if I recall correctly) - in that climate, suitably quarantined infected plants may dry out quickly, but I doubt this would be the case in the UK (except during a hot dry summer heatwave). I suppost is may just work if you catch the infection very early, when the first slight symptoms appear.

    Anyway, I guess the use of Trichoderma as a preventative measure (mixed in with the Ping substrate and / or administered via watering) is certainly worth investigating. Now I'm off to find the best source of Trichoderma in the UK...

    Many thanks again for the help and information! :tu::D

  3. Hi Stephen,

    Many thanks for the reply and pointer: from searching via Google for Fusarium and Trichoderma, I found a few links suggesting that the latter can indeed be effective against the former, e.g.:




    So it looks like a dose of Trichoderma for the Pings in future!

    Will Trichoderma colonize and live successfully in the very open / loose mainly mineral-based Ping mix that I use? It consists of 6 parts Seramis, 2 parts Perlite, 2 parts Vermiculite and 1 part "Soil" (where the "Soil" component is: 2 parts John Innes Number 2 loam, 1 part Moss Peat, 1 part Fine-Grade Orchid Bark [steralized pine bark + charcoal] and 1 part Sharp Sand [or Silver/Silica Sand]). I usually add a handful of powdered lime to this, at least for calcium-loving species + hybrids.

    Thanks again Stephen. :tu:

    Any suggestions now of suitable Pinguicula-compatible nematicides (anti-nematode products)? I guess though that if I can combat the Fusarium (Crown-Rot Fungus), the nematodes can be left in peace? It's always useful though to know of extra defence options, if required! Thanks. :D

  4. Hi,

    Does anyone know of any anti-nematode (nematicide) or fungicide products that are compatible with Pinguicula, and could for example be mixed in with the soil mix during preparation to aid at least as a preventative measure against "Browning Heat Disease" (Fusarium or related fungus + nematode damage)?

    I have had a few problems with this during the autumn and winter, mainly in plants which were purchased already growing in a "standard CP mix" containing a large proportion of peat, and they have succumbed before I could repot them into my standard open free-draining Ping mix (which I was intending to do in spring - I guess I should have repotted them sooner). I have kept most of my Pings just damp to bone dry (depending on species), but have still lost a few (mainly P. 'Tina', but a few others too), which is extremely annoying as my CP collection is at a low ebb anyway and I hope to start rebuilding it in 2007 (concentrating on Pinguicula).

    And before anyone mentions it, growing warm and wet under lights is not an option for me (too expensive!). I grow the plants in natural light, at the moment indoors on an East-facing windowsill (until I can set up my greenhouse in spring as a specialized Ping grow-area).

    So any ideas on the above (in particular any helpful anti-Fusarium and / or nematicide) to help as a preventative would be very welcome.

    Many thanks...

  5. Hi Joseph,

    Those are interesting observations regarding fragrance in Pings.

    I would guess that species with pale-coloured or white flowers may be more inclined to have a scent, perhaps to attract nocturnal insects. Also, as you say, some fragrant flowers are only fragrant at certain times of the day (e.g. evening or night).

    Also, according to Donald Schnell in his book "Carnivorous Plants of the United States and Canada - second edition", at least 2 species of Pinguicula from the South-East USA (P.planifolia - see page 318 under "Description", and P.ionantha - see page 321 under "Description") have what he describes as a "sweet honey-like" fragrance: do you grow these plants, and if so have you noticed this scent? (Unfortunately I do not [yet!] grow either of these species).

    It would be great to try to select strains of plants (species or hybrids) for fragrance, which would make them even more attractive commercially.

  6. Fantastic photos Jan - thanks for sharing them!

    In the "CP Habitats" section, I especially loved the following 3 shots of a very unusual habitat for Pinguicula vulgaris:




    Growing on the walls of an old castle - amazing! :shock:

    Thanks again... :D

  7. Hi Vic, Sean,

    Thanks for the advice. Hmmm... tricky one, I'd love to see the flowers, and didn't realise that you had to have such a large cluster to produce flowers (I think I read somewhere - perhaps a previous post here? - that they can flower with much smaller clusters (say 6 - 10), but that it's very unlikely, and yes, I would like to see some flowers in my lifetime! :( (10 years is a bit of a long wait!)

    I'll probably source some extra clusters for the people I want to send some to then from somewhere else.

    Thanks again! :D

  8. Hi,

    I have a nice cluster of Utricularia menziesii tubers (8 tubers at the moment - I think it was 5 last summer when I received the plant), and I promised a couple of spare tubers to 2 people, so I want to divide my clump now that they are in the middle of dormancy in our Northern Hemisphere summer.

    Are there any special techniques of doing this? I want to take off 2 sets of 2 tubers each (which would still leave me with a cluster of 4 tubers), but leave them joined in their own "cluster" if possible. How are the tubers attached to each other? (I haven't yet closely examined them).

    I must admit, U.menziesii seems an easy and fascinating Utric to grow - I haven't seen the flowers yet (and obviously me taking off divisions could delay this by a year or two!), but am looking forward to the event when it happens!

    Many thanks... :wink:

  9. Many thanks for the replies - I also thought it was U.minor, but having never seen a wild Utric before couldn't be sure.

    Looking at the distribution maps, the only 2 Utricularia species in this particular area are U.australis and U.minor, and it certainly doesn't look like the photos of U.australis that I've seen (much too small in flower and stolons, and different flower shape and colouring).

    Thanks again... :wink:

  10. Hi Pablo,

    Just out of interest - what altitude (i.e. metres above sea level) are these plants growing at?

    Also, what are the black spots on the leaves in the second photo (with the close-up of the flower) ? Initially I thought they were captured insects, but on a closer look they look like something else (too "flat" and "fuzzy" to be prey?), so now I'm not so sure - maybe a fungus or something similar? Just curious... :wink:

    Once again, they are wonderful photos. :wink:

  11. Hi,

    Can someone identify the following aquatic Utricularia species please?



    I have my (very strong) suspicions as to which species it is, but would like confirmation from those more knowledgeable, just to be sure! (I won't mention what I think it is, so as not to influence any ideas on the subject). The flowers were very small, but nevertheless attractive.

    Myself, Langford Williams ("Langy") and Ian Salter went on a fieldtrip to Cors Fochno (north of Aberystwyth on the west Wales coast) and the surrounding hill area yesterday (Monday 19 June 2006), to see the orchids and CPs. We had a very successful trip, seeing all three native UK Drosera (D.anglica, D.intermedia and D.rotundifolia - all in great abundance), not to mention several D. x obovata (D.anglica x D.rotundifolia) hybrids, the Utricularia species shown above, and in the hills in the area, Pinguicula vulgaris - also some stunning orchids in the nearby Ynyslas sand dunes (and a few Dactylorhiza maculata in the bog itself)!

    I'm sure one of us will start a thread about the trip in this section of the forum soon, but in the meantime, I would love to positively ID the Utric. Langy first spotted these, growing in a Sphagnum "slurry" in a wet ditch. There were quite a few of these flowers in a small area of flooded sphagnum ditch. In a way, for me at least, this was the best find of the day, as prior to this I had never seen a Utricularia in the wild, so it was wonderful! The fact that we got to see members of all the native UK CP genera (Drosera, Pinguicula and Utricularia) on one day trip was fantastic! :P

  12. Hi Peter,

    Many thanks for the photos - it's great to see the plants in the wild, but sad to think that human-accelerated global climate change could have a dramatic impact on these and similar plants (and animals of course) - they just won't have enough time to evolve and adapt to the new conditions as the changes will be too rapid (centuries or millenia instead of 10,000's to millions of years), thus I fear for the continued survival of these wonderful living gems. :cry:

    Nevertheless, many thanks again, and I hope that the rains come soon. Also, I know too well how hard it is to take good photos in the field (particularly on a windy day). I look forward to seeing more of your photos in the future. :lol:

  13. Hi Tim,

    Thanks for the confirmation - I'm now 99% certain that the second plant is Pinguicula potosiensis 'Green Leaf Clone'.

    This first I think is either a clone of P. hemiepiphytica, or a hybrid that probably at least involves that species (e.g. P. hemiepiphytica x P. laueana or P. hemiepiphytica x P. moranensis). So it will remain a bit of a mystery for now, until I can propagate and distribute it to more knowlegeable Ping growers (both because I think it's a nice plant, and for identification purposes!).

    Thanks again for all the ideas! :D

  14. Hi,

    Well, this last Monday (12th June) I decided to go hunting for CPs in a range of hills not too far away from my home called the Preseli Hills. These are in North Pembrokeshire, Wales, and aren't that high - up to about 600m. This is also known as "bluestone country", and is where the original stone was gathered from to create Stonehenge many miles away.

    Anyway, there are lots of photos in this post, and they were all taken in the field quite late in the day (I didn't leave home until 5pm - a bit late really!) so may not be of the best quality - but I hope you can enjoy them a bit anyway. At least they give a reasonable view of the landscape of the area, and the habitat of the plants. They may be a bit repetitive in places, as I'm trying to convey a "feel" for this lovely location as well. Also, they are in chronological (as opposed to logical!) order.

    I went to 2 locations actually - firstly to a small area of heathland just to the north of the hills, to search for Pinguicula lusitanica (I was unsuccessful this time, but will return next month, plus search in different areas - but I did see some nice native orchids), and second onto the open hills and moorland, to look for Drosera rotundifolia and Pinguicula vulgaris (Drosera intermedia is also in the area, but I will search for that another day...).

    PART 1 - Heathland Orchids:

    1. Dirt track through small area of heathland - orchid habitat:


    2. View of some of the orchids growing by the track:


    3. Orchid - probably Dactylorhiza praetermissa, but looks like a small amount of introgression with D.maculata:


    4. Orchid - looks like more-or-less pure Dactylorhiza praetermissa:


    5. Orchid - a paler D.praetermissa (possibly introgressed with D.maculata ?):


    6. Orchid - Dactylorhiza praetermissa (probably! - Dactys are sooo promiscuous :shock: ):


    7. Orchid - now this looks more like plain Dactylorhiza maculata:


    8. Orchid - a lovely hybrid, I would guess D.praetermissa x D.maculata (note the "loop" pattern of speckles on the lip):


    9. Orchid - the above plant, showing the entire flower spike. This was a robust and beautiful plant (as are many Dactylorhiza hybrids):


    PART 2 - Preseli Hills + CPs:

    10. Landscape - a view from close to the car parking area:


    11. Landscape - another view:


    12. A shot showing drifts of the beautiful Cotton Grass (Eriophorum vaginatum), which was abundant everywhere on the hills:


    13. More Cotton Grass:


    14. More Cotton Grass - the seed heads glowing in the sun:


    15. Another large drift of Cotton Grass:


    16. Yet more Cotton Grass, showing how it often grows in large mats of swampy Sphagnum moss, along with CPs - can you tell that I like Cotton Grass ? :lol:


    17. At last! The first CP! Drosera rotundifolia:


    18. A nice view (yes - Cotton Grass in the foreground!). The bogs and heaths at the northen foot of the hills (across the middle of the photo) supposedly hold populations of Pinguicula lusitanica - like looking for a "needle in a haystack" I would guess!


    19. Another view, to the north-east of the hill ridge:


    20. Another shot of a Drosera rotundifolia. One of my interests, after seeing Siggi Hartmeyer's excellent "Snap tentacles and runway lights" DVD, is investigating the occurrence of snap tentacles in D.rotundifolia (probably the only native species likely to possess them), especially as Siggi states that they don't occur in the hibernaculun-forming species, yet I have seen them myself in D.rotundifolia - albeit they do not appear consistantly. A good topic for investigation I think. Anyway, in the following photo, a snap tentacle is just visible (top left of the right-hand leaf):


    21. A closeup of the snap tentacle:


    22. A view looking back towards the coast (the weather started to deteriorate late in the afternoon):


    23. A view towards the distant Pinguicula vulgaris site:


    24. Getting closer to the Ping site!


    25. I love the patches of sunlight that move across distant hill slopes (obligatory sheep in foreground!):


    26. The CP site is the light coloured patch just to the left of the pathway, in the middle distance in the photo:


    27. Habitat shot for the Pinguicula vulgaris (and Drosera rotundifolia) site, which is a peaty hillside seepage:


    28. Close habitat shot (how many Pings can you see in this photo?! Yes, there are some! :lol: ):


    29. Closeup of a P.vulgaris flower, from the front:


    30. Side-view of flower:


    31. Butterwort rosette in situ:


    32. The Pinguiculas were growing alongside Drosera rotundifolia at this site, which in my experience is fairly unusual (P.vulgaris often prefers damp rocks, often in alkaline conditions [though certainly this is not always the case]):


    33. Another D.rotundifolia at the same site:


    34. More P.vulgaris rosettes:


    35. Another shot of the Sundews and Butterworts co-habiting:


    36. The Ping flowers rise high above the rosettes, which are often hidden below dead grasses - the flowers are sometimes the only easy way of locating the plants at this site (but where this species grows on wet rocks, as it often does elsewhere, the almost luminous-green rosettes are obvious, looking like starfish against the dark rocks):


    37. More rosettes:


    38. Another close habitat shot:


    39. Sundews growing lithophytically on a thin layer of (non-Sphagnum) moss on a rock in the middle of the seepage:


    40. Butterwort and Cotton Grass in middle of the seepage:


    41. Another overview of the wetter area of the habitat:


    42. Another Ping (note captured prey in tip of the top left leaf):


    43. Another habitat shot, overview of the rocky peaty spring (and my groundsheet, used to kneel in the damp to take photos!):


    44. Two more butterwort rosettes, showing how concealed they can be at this site:


    45. Some more Ping flowers:


    46. Another closeup of the flower:


    47. Last overhead shot of habitat, with 2 Pings (centre and lower centre of photo):


    48. View to the south of the site:


    49. Last habitat shot - view to the north (Ping + Drosera site in foreground):


    50. Looking back towards the car (a long walk!) and coast - around 9:45pm:


    51. Sunset over the coast (I was still a long way from the car though!):


    52. Another sunset shot:


    53. And another (about 3 minutes before the sun disappeared)!


    54. The Cotton Grass looks particularly beautiful - almost luminous - in the evening dusk light (around 10:15pm):


    *** THE END! *** (Phew!! :lol: )

  15. Thanks for the suggestions. :wink:

    I think the second plant is now probably P.potosiensis, as Eric says.

    But I'm still not sure about the first plant! To me it doesn't "feel" like any form of P.laueana (it's larger, stockier & more robust, the flower stalk is thicker and the flowers are larger, for example, than my P.laueana 'CP2' plants - also the petal tips are more rounded, less "square"). The summer leaves are not yet fully formed, so you can't really go by the photos for these. To me, it could still be P.hemiepiphytica, or maybe a hybrid involving that species (e.g. P.hemiepiphytica crossed with P.laueana or P.moranensis). Ah well... maybe I should propagate and distribute it to Ping enthusiasts for ID purposes!

    Incidentally, I *do* have (hopefully!) a "true" form at least of P.hemiepiphytica, from Andreas Wistuba, although it hasn't yet flowered for me...

    Thanks again for the help and comments.

  16. Hi,

    I have a couple of Pinguiculas that I would love to have the correct ID for (or at least a good idea of what the could be).

    Apologies in advance for the quality of the photos, they were taken in haste!

    1. Pinguicula #1:

    I received this plant at the CPS AGM at Reading University in 2003 from Phil Adedeji, labelled as Pinguicula hemiepiphytica. It certainly has at least some of the characteristics of that species, but not as pronounced white markings as in the photos I've seen before of this species. Of course, there could be several clones of this species floating around. It certainly has similarities with 2 photos I've seen of this species by Fernando Rivadavia of plants in the wild from Eric Partrat's excellent website - see:




    (note: no white "streak" patterns easily visible in these photos).

    Alternatively, it could be a hybrid, possibly involving P.hemiepiphytica (maybe with P.laueana or P.moranensis, or something else ?).

    Anyway, here are the photos:

    1. Flower from front:


    2. Flower from side (note long spur, thicker for half its length):


    3. Summer leaf rosette (just emerging from large winter succulent rosette):


    Any ideas / comments ?

    2. Pinguicula #2:

    I purchased this plant a couple of weeks ago from Paul Gardner, of P & J Plants: he had received a batch of them from the Netherlands (I assume Carniflora ?), but I can't find anything like them on the Carniflora web site. I'm assuming it's some sort of clone of P.moranensis, but is this true? And if so, which one?

    Note: the flowers are actually a lighter bluish-purple / "mauve" than is shown in the photos.

    Here are the photos:

    1. Flower from the front:


    2. Another view of the flower:


    3. Summer leaf rosette:


    Any ideas / comments ?

    If anyone can provide any "leads" to follow up, or any educated guesses / comments, I would be very grateful - many thanks! :thumleft: :D

  17. Well, I'm far from being a Utric expert, but as Utricularia australis is a UK native species, I would assume it is fine in an iced-over pond. Maybe best to make sure your plant is from a European clone though. As for the "too fertile water" - not sure, sounds like it may have too many nutrients, but maybe a more seasoned Utriculariophile can answer that one?
