  1. Happy World Carnivorous Plant Day (May 4), Here is our contribution to the WCPD of the International Carnivorous Plant Society, ICPS. Irmgard and I wish you much pleasure!
  2. Nepenthes & Triphyophyllum At the beginning of the 2022 season, we first take a look at our pitcher plants that have well survived the winter in our greenhouse. Especially the cross Nepenthes veitchii x edwardsiana - unfortunately not for sale - is very popular with our audience, but also her mummy, N. veitchii as well as N. ventricosa "Porcelain" do not need to hide. We will show some more species and hybrids, and then come to an attraction that, although still very small, joined our collection last summer: The largest carnivorous plant in the world Triphyophyllum peltatum. This liana can grow over 70 m long and we show photographs of its flowers and flyable seeds in the W├╝rzburg Botanical Garden. For the unique photos, excerpts from our film "Triphyophyllum peltatum", we thank Dr. Heiko Rischer, Dr. Jan Schlauer and Stewart McPherson. Enjoy! Finally, we would like to mention the World Carnivorous Plant Day 2022 of the International Carnivorous Society ICPS on May 4. The organizers and contributors have put a lot of effort into presenting exciting lectures and films on the internet during this day. We were also invited to produce a movie for it, so we turned our living room into a "green hell". More is not revealed, everything else on the internet on May 4 at the ICPS (
  3. Drosera cistiflora 2022:
  4. Greenhouse Nepenthes Part 3 (English subtitles provided) This time we show a special hybrid, Nepenthes eymae x clipeata, which we received as a small seedling from Paul Debbert in 1991. In the meantime it became a flowering female with many active pitchers on the long shoots. Adventurous is the story of our N. mirabilis "Cairns", which developed splendidly since 1995. For this we make a short excursion to its natural habitat in Queensland, Australia. Our N. ramispina forms plenty of pitchers as well as the N. rafflesiana var. alata, already presented in the 2nd part of our Nepenthes series, which developed into a real feast for the eyes with currently 22 active upper pitchers. Enjoy!
  5. Nepenthes talangensis x lowii, a beautiful hybrid made in Weil am Rhein.
  6. Cold House Carnivorous Plants Flowering Today we visit the carnivorous plants in our cold house, where magnificent sundews are currently blooming, which have been growing here for 20 years. An impenetrable tangle of glue traps, glowing in the sun, is formed by the Australian Drosera planchonii. With particularly splendid blooms inspires the South African Drosera cistiflora as well as the Tibet orchid, Pleione formosana and our Drosophyllum developed quite worth seeing over the years. The current generation had sown itself in spring 2019 here in the cold house without our assistance in a pot with the American butterwort Pinguicula planifolia. Even after two years, dewy pine and butterwort are thriving perfectly together, and in the meantime sundew and bladderwort have joined them on their own. Enjoy!
  7. 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):
  8. 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 will show you the development of the seed pods of our N. bicalcarata female, of which at least a few are starting to swell after the pollination end of December. Unfortunately, no more cuttings can be pre-ordered at the moment, the demand was simply too great. Enjoy!
  9. 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)!
  10. 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. While exchanging data with a colleague, the latter was so impressed that he submitted the "Diva" and the Bladderworts to Guinness as a record-breaker ... and this was accepted. A great story.
  11. 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)!
  12. 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 experiments, the genus Utricularia (using U. australis as an example) was recorded too as the fastest aquatic predatory plant. We would like to take this opportunity to thank particulary Richard Davion (Adelaide, AUS) who was the first who reported about it, and all those who have supported us over the years in the research of snap-tentacles! If you want to see the experimental plants examined at the University of Freiburg in action, I recommend our topic "Carnivorous Plant Speed Contest":
