  1. Nepenthes are tropical, their seed has no usual inhibitors to germination. They easily germinate in appropriate conditions, if they are viable. I might expect that GA3 could cause more trouble than its worth to obtain, prepare, and apply to fresh, highly viable seed. My understanding is that it is used with difficult to germinate seed, seed that has inherent germination inhibiting systems in place. It might even cause abnormal germination and subsequently abnormal growth, if used. However, if the seed is old, and you anticipate that normal viability is strongly compromised due to age, it may be beneficial to pretreat the seeds with a very dilute GA3 solution, just prior to sowing. In that circumstance, you may achieve better germination, than with just normal germination regimens. My usual plan, with old, or seed of very low expected viability, is to surface sterilize them, then sow them in vitro. If done well, it is easy to see if there is any viability remaining in the seed.
  2. Here is one of the plants from the pic in my first post to this thread. It was moved up to its own 2.25" (5.7 cm) pot. It is nearly finished transitioning to winter-form leaves.
  3. I started many Mexican Pinguicula, in 100% moss peat (peat moss), first. They did well. Then I read Eric Partrat's site Pinguicula.org, and decided to try various media ingredients and combinations thereof. I discovered very little, if any difference in health or growth performance, no matter what media I used, as long as I gave them very strong flourescent lighting, weak and frequent feeding with dried insect powder and weak soluble fertilizer solutions, and kept them nearly semi-aquatically, year-'round. There are a few species that do not thrive in these conditions, but the majority do. The list of ingredients and combinations, I've tried, is extensive. Yet, I'm sure I haven't tried every combination that would be suitable. I haven't yet found any that aren't.
  4. I agree, a strong resemblance to Pinguicula 'Sethos'. It most likely is that cultivar. It has no resemblance to any form of Pinguicula ehlersiae. It may simply be a mislabel confusion. Some people, who aren't that familiar with the various species, hybrids, and cultivars of Mexican/equatorial Pinguicula can make such mistakes. When I first began my interest in these plants, one of the first plants I acquired was identified to me as Pinguicula 'Weser'. It wasn't until I had propagated it and given away several dozen divisions, that I realized its true identity was Pinguicula 'Sethos'. I had many people to notify of my error. As you can see, I also had photographs to edit.
  5. you wouldn't have any Drosera regia roots to spare I cant find any locally

  7. I believe what will9 is saying is that unofficial, unregistered names abound, while official, registered cultivar names are scarce. That many or most growers ignore the official naming conventions (coordinated by the ICNCP), that are carefully followed with most other plant groups. By looking through the various Sarracenia plants linked through the CP Photo Finder, most have "bogus" names, few have validly registered cultivar names.
  8. Those original names, given to natural hybrids, originally believed to be species, such as Sarracenia x catesbaei, are considered by some, to be invalid - opting rather for the appropriate hybrid formula. I am also beginning to lean this way, myself. If you choose to opt for these formula, in lieu of the quasi-official botanical names given to some of the primary hybrids found in the wild - you may find it simpler, or perhaps not. Hybrid formula can be written in several ways: The symbols designating the sexes of the parents can be used and the parents can then be written in any order, even alphabetically -- Sarracenia psittacina x flava Or they can be written in parent order, with maternal parent listed first -- Sarracenia alata x minor
  9. With nearly optimal growing conditions the foliage of these closely related species is somewhat distinctive, though just barely. In less than optimal conditions the vegetative parts become less well defined, hence, less distinctive. Some growers question if perhaps; Pinguicula esseriana, Pinguicula jaumavensis, Pinguicula ehlersiae, and Pinguicula debbertiana, may simply be slightly different forms of the very same species.
  10. The first book, Carnivorous Plants, 1979/2005 is a very different book from the second book, Insect Eating Plants and How to Grow Them, 1988, published between the two editions of the first book. Though I'm not sure that you're talking about the two different titles and not different printings of the same book. If you're talking about two different printings of Carnivorous Plants, and I believe you are, there are probably a few typo's corrected in the second printing, though I may be mistaken. There may also be a few other differences. I have a copy of the first printing and Genlisea is misspelled, and a few other words in the volume. I remember reading a book review, somewhere that discussed the differences, though I haven't been able to find it again, yet.
  11. Yes, the 90 grit is a "sieve number", and basically translates to passing a screen with 90 wires to the inch / 2.54 cm. It is a very fine sand (90 grit = 0.150 mm diameter). Silt particles are smaller, between 0.002 mm and 0.063 mm, larger particles than this are sand and smaller are considered clay. I believe that when fine sand particles like this are thoroughly blended with the peat moss, they help the peat re-wet if it becomes dry, due to their capillary attraction for water, verses the peat being hydrophobic. However it works, this media mixture seems to provide a very good substrate for Sarracenia. One caution, let it regularly drain thoroughly or anaerobic conditions may develop with undesirable or even dire consequences.
  12. Sometime back in the late 1960's or early 1970's I visited Leo Song at the greenhouses of CSUF (California State University, Fullerton). As part of an experiment concerning germinating seeds of various Sarracenia primary hybrids he had a great many Sarracenia seedlings that were growing in what were/are called 2" rose pots. He gave me about a half-dozen or so of these seedlings. The media in these pots, was an obvious combination of fine, 90 grit silica sand, perlite, and peat moss. The seedlings growing in this media were doing very well. I mixed various combinations of these three ingredients until I had a media that matched the appearance of the media these seedlings were growing in. It seemed like a very suitable media, all the seedlings were quite robust. I remember they were only a few years old, but I had to cut the pots away from the rhizomes in order to avoid harming the plants, they were so tightly wedged into the pots. I remember as I potted them up, most had rhizome buds or branches that I was able to use to propagate divisions with. I planted them all in this same sand/perlite/peat mix, including the larger plants. All seedlings continued to grow very quickly in this media I had "duplicated". So, credit for my favorite Sarracenia media actually belongs to Leo Song. Even though my formula is only an approximation of the mix he originated. I propagated and distributed between fifty to one hundred or more of each of these original seedlings until I had to leave most of my CP collection behind when I had to suddenly relocate from Oak Harbor, Washington to Southern California. It may be true that perlite varies in physical properties and pH depending of how it is processed and/or where it originates. But I've only ever dealt with perlite distributed exclusively for horticultural purposes. --- --- --- --- --- --- --- --- --- --- --- --- I've often been annoyed how some of the perlite would float away during watering, so I learned to water gently from above and frequently enough to keep the plants at or near an optimum media moisture level. I have successfully used and seen others use many different media mixtures and ingredients, but this mixture is one of the most simple and reliable.
  13. For most Sarracenia I like using a media of 3 parts 90 grit silica sand, 3 parts perlite, and 2 parts peat moss.
  14. Howdy Amar, You are correct, Drosera spatulata Hong Kong, as published in "Savage Garden", is not a validly registered cultivar. It does not meet all of the requirements for cultivar registration, so its registration is incomplete, see --> D. 'Hong Kong'. I don't believe the original publication even included a photographic standard. Cultivar names, such as Drosera spatulata 'Ruby Slippers' can be correct when written several ways; Drosera 'Ruby Slippers', Drosera spatulata 'Ruby Slippers', or D. spatulata 'Ruby Slippers'. See, ICRA Name -> "HOW DO I FORM A NEW CULTIVAR NAME? The full name of a cultivar will always begin with the name of the genus to which the cultivar belongs. Optionally, the species or hybrid epithet may be included as a second element in the entire name but this is not usually necessary; inclusion of such epithets merely provides more information about your cultivar" Here is a link to the published standard photograph for Drosera 'Ruby Slippers'. The main reason I chose to register this cultivar is that Drosera 'Ruby Slippers' closely resembles a large Drosera brevifolia. Drosera brevifolia was the very first Drosera species I ever found growing in the wild. I was amazed at how dry the soil was where I first found a small colony of them. I also find the wedge-shape of its leaves and intense dark red coloration (when growing in strong light), to be quite attractive. Whether or not your Drosera spatulata from Hong Kong is the same as the one Peter D'Amato wrote about in "Savage Garden", it would probably be best to ask Peter for his opinion. I think he is active on the CP Listserv. Of course, just because the cultivar, Drosera spatulata 'Ruby Slippers' allegedly originated from plants reported to be collected from Kowloon Peak, Hong Kong, does not necessarily follow that all Drosera spatulata from Hong Kong are Drosera spatulata 'Ruby Slippers', or any other specific clone or cultivar. There are so many different forms of Drosera spatulata, it would be nice if more of them were registered as cultivars. However, it seems quite challenging to describe their subtle, yet unique differences, in order to qualify them for cultivar status - I still feel it should be attempted. An additional question I would pose to the CP ICR, would be: Does the preliminary, yet incomplete registration of Drosera spatulata 'Hong Kong' reserve that cultivar name, awaiting the original author's completion, can it be completed by a new author, or even independently published by a new author?
  15. Some or all leaves may die back as you describe, if the rhizome has died or if they're subjected to exceptionally cold temperatures. Without direct physical examination it is difficult to absolutely determine fatal root-rot. It is best to wait until Spring, when conditions for growth return, before examining the rhizome to make a final determination.
