  1. You are welcome, the seeds came from our Veitchii female, pollinated and harvested at our greenhouse in 2016. So the plant in the video is about five years old. They grew slowly because I rarely gave any fertilizer. Haha, large Neps will soon need much place . Edwardsiana pollen came from a friend. This is our mother plant N. veitchii "Highland" in 2014. Meanwhile the source of even more hybrids like N. veitchii x bicalcarata (still quite small):
  2. NEPENTHES 4 CUTTINGS This time we are looking in our greenhouse for pitcher plants (Nepenthes), for which because of their attractive pitchers we often get requests for cuttings from you. First of all, there is Nepenthes rafflesiana var. alata, which is much sought after because of the striking frills on its lower pitchers, and which also forms quite large upper pitchers. Similarly often asked for is N. ventricosa "Porcelain", which as the name suggests is popular because of its porcelain look lower pitchers. Before we take a look at our most popular hybrid N. veitchii x edwardsiana, we w
  3. Trichome or tentacle? The active traps of Byblis and Drosera. Both the Australian rainbow plants (Byblis) as well as the sundews (Drosera) catch their prey with active, that means moving sticky traps. Nevertheless, there are serious differences between the two carnivorous genera, which we show in this short film with exciting microscope and time-lapse shots. It is explained in an easily understandable way, why the adhesive traps of the Byblis consist of hairs and those of the Drosera of tentacles. Good entertainment (English subtitles provided)!
  4. A successful and especially healthy 2021 to all of you! Today we are of course especially happy about the entry of "our" Diva into the Guinnes World Records 2021. The photo also shows the important players: On the top left the photo of Richard Davion, who was the first to report about the fast catapults. The right photo shows Dr. Simon Poppinga, group leader in the Plant Biomechanics Group at the University of Freiburg, who, in collaboration with the Hartmeyers, measured the fabulous 75 ms for a capture with a high-speed camera and coined the name catapult-flypaper trap. Whil
  5. Pollinating Nepenthes bicalcarata: A couple of the large pitcher plant Nepenthes bicalcarata grows in a pot in our greenhouse and even flowers simultaneously. This film shows how we pollinate the dioecious plant. Enjoy the film (English subtitles provided)!
  6. New in Guinness World Records 2021 The catapult flypaper trap Drosera glanduligera has now been included in the Guinness World Records 2021 as the fastest terrestrial predatory plant. It is actually faster than the VFT. Together with Dr. Simon Poppinga and the team of the Plant Biomechanics Group of the University of Freiburg, Irmgard and I are very happy about this great success of our common research work on the "Diva" (catapult-flypaper trap published 2012 in Plos One). Simon and the participating authors are additionally pleased, because based on the results of their experi
  7. Mantis vs. Sceliphron on Nepenthes bicalcarata. The digger wasp Sceliphron caementarium captures spiders for its brood, so it is quite fortified; however, the adult wasps feed on vegetarian food. These wasps are quite crazy about the nectar on our N. bicalcarata couple. A couple of spontaneously intruded praying mantises lurks from their branches below our greenhouse roof, which inevitably leads to an encounter of the predatory insects. Who is going to become the booty? Here the shreds fly: Exciting pictures from our CP-greenhouse with extra spooky soundtrack. Enjoy!
  8. Welcome to our carnivorous plant speed contest! Four carnivorous genera qualified for our speed contest and they all give their best. Is Aldrovanda able to keep up even against the water resistance? How well does the famous Venus flytrap? Does the sundew that is usually regarded quite sedate have a chance at all in this competition? And what's the story with the southern bladderwort? Examined in detail with the help of time lapse as well as slow motion shots. English subtitles provided, enjoy! Special thanks go to Dr. Simon Poppinga and his team of the Plant Biomechanics Group of the U
  9. Sarracenia leucophylla: Attention Bee Trap (English subtitles) With its shiningly white patterned leaves Sarracenia leucophylla is certainly one of the most distinctive pitcher plants. We observed the impact of this large carnivore's attractivity to insects in the surroundings quite coincidentally in summer 2019. Suddenly, a whole ant colony had vanished that we observed for weeks in the frame of experiments with Venus flytraps. Looking for the reason, we did not only find the missing ants. Thereby, we unfortunately also found many dead honey bees. We kept an eye on this during the season
  10. In literature, Byblis is usually described as a passive flypaper. But new examinations (2018/19) show that the genus possess active moving capture hairs. A highlight for CP-enthusiasts! In 2018, first videos by Dr. Gregory Allan (GB) on Facebook showed an active motion of Byblis trichomes. However, the topic literature describes the carnivorous genus as immobile. To review that behavior, we made own time lapse shots with a microscope that turned out to be surprisingly even for ourselves. They confirm clearly that the unicellular trichome stalks show an active motion down to the leaf surfa
  11. Nepenthes truncata and N. veitchii capture five house mice, but no shrew. This winter, we had a whole shrew family (Soricidae species) in our greenhouse. These predators are not interested in Nepenthes nectar; therefore, none of them became captured. If house mice come for a visit, things look very different. Here is our film on the overall five house mice (Mus musculus), meanwhile captured by Nepenthes inside our greenhouse.
  12. The catapults of the sundew Drosera glanduligera fling passing prey animals in a sensational manner onto the sticky trapping leaves. Already in 2012, we measured and published this enormous - 75 ms - speed for a capture event, in the labs of the Plant Biomechanics Group of the University Freiburg (Germany). In this film, we show again by measurements with Dr. Simon Poppinga at the labs of the bionics specialists in Freiburg, what an amazing force these catapults possess. A single catapult has an average weight of 0.15 mg. The rapidly flung fruit flies in our former experiments weigh 1.74
  13. Vegetarian Carnivores. The first video in our new series "Siggi's CP Info" Is it possible to grow your carnivorous plants with vegetarian diet? Our first film from the new “Siggi’s CP Info” series provides the answer. Carnivorous plants predominantly capture and digest arthropods like insects, spiders or little crustaceans. Some of the largest tropical pitcher plants are even known to eat real meat, mostly small vertebrates like mice or reptiles. But what happens if you feed vegetarian food to the carnivores? Even Charles Darwin pointed out that in times of high pollen abundance the
  14. Never fear! You do not need a chemistry book to understand this film. Showing a bunch of beautiful sundew species and hybrids, we explain really briefly and clear why particular chemical ingredients of the sundews are not only interesting as cough medicine for homeopathy, but also as traits for taxonomy, in a manner as comprehensible for laypersons as possible. The featured chemical analysis (TLC) is helpful for the description of novel species and gains an additional dimension by the fact that most true species produce only one naphthoquinone or none, while hybrids show the chemistr
