JanW Posted July 24, 2003 Report Share Posted July 24, 2003 The propagation of the petiolaris complex sundews is very easy. The start was made by Joseph Clemens with D. falconeri. Read the whole story here: http://www.cpzine.com/article.aspx?cid=13&...p;m=10&d=13 There are some other species we tried as: D. dilatato-petiolaris, D. paradoxa and D. petiolaris [EDIT: No -> D.dilatato-petiolaris, too...]. All work very well, especially by just pulling the leafs from the plant with the white base and then put them in pure destilled water, in bright light and some heat. The success rate is about 75%, so go on and propagate your little gems! ;) The tread lost here is on the petflytrap forum, too: http://www.petflytrap.com/cgi-bin/ib3/ikon...f=5;t=394;st=25 I hope this forum will fill quickly again!

AdamH Posted July 24, 2003 Report Share Posted July 24, 2003 Hi Jan, Thanks for the information. I hope to start growing the Drosera petiolaris-complex plants (also known as the "woollies"!!) soon, indeed I will be sowing some D.ordensis seeds today in a heated propagator, but I need to make a special grow area / terrarium for them first, and any ideas / hints / tips for that would be very welcome. What conditions do you grow them in? Quote Link to comment Share on other sites More sharing options...
Tim Posted July 24, 2003 Report Share Posted July 24, 2003 I got a small falconeri from Joseph AKA Pinguiculaman about 8 months ago, and it hasn't died yet, but it is the same size. The greenhouse is unheated, and I supect this is the reason, but I think they are only easy if the conditions are rather particular. Quote Link to comment Share on other sites More sharing options...
Tim Posted July 24, 2003 Report Share Posted July 24, 2003 After almost a year, this is the best I've done with this plant, and short of increasing heat, I'd love suggestions. Quote Link to comment Share on other sites More sharing options...
Tim Posted July 24, 2003 Report Share Posted July 24, 2003 Then I guess I will have to donate it to a good home if it ever comes out of dormancy. Either that, or bite the bullet and get a gas heating system. Quote Link to comment Share on other sites More sharing options...
JanW Posted July 24, 2003 Author Report Share Posted July 24, 2003 Hi, I grow my plants of D. petiolaris [Edit: D. dilatato-petiolaris] on a sunny windowsill in a small plastic terrarium which stands on top of the lights of another terrarium. The box is covered with plastic by 80-90%, so it gets very wet and hot inside. They benefit much from the heat from the lights they are standing on. Perhaps I will buy a terrarium heating pad for the winter time. You can see some pictures on my homepage, but the plants look much better now! And see the petflytrap thread, too. I posted some pics there, too. Sorry for the few tips, but for the time being I only succeed in propagating this little gems, growing them is another side of the coin! ;) Sorry for the bad english! Good growing! Jan Quote Link to comment Share on other sites More sharing options...
Tim Posted July 25, 2003 Report Share Posted July 25, 2003 That's good advice, thanks. Quote Link to comment Share on other sites More sharing options...
sundewmatt Posted July 25, 2003 Report Share Posted July 25, 2003 Hi Tim. Have you thought about putting a dome over the falconeri so the sunlight heats it up during the day? Matt Quote Link to comment Share on other sites More sharing options...
sundewmatt Posted July 25, 2003 Report Share Posted July 25, 2003 I have torn a couple of petiolaris complex plants apart as experiments to try to propagate them and had no luck. I will probably try again sometime soon, though honestly I am up to my eyeballs with them now - they germinate really well for me.

JanW Posted July 25, 2003 Author Report Share Posted July 25, 2003 Hi, not everyone has more than one clone to produce seeds or a good source for them. Why don't you try this method and share some spare plants? ;) Good growing! Jan Quote Link to comment Share on other sites More sharing options...
sundewmatt Posted July 26, 2003 Report Share Posted July 26, 2003 Hi Jan, I do - I trade and sell my spares, but I only ship within the US. Please email me privately through my website if you're interested. Thanks, Matt Quote Link to comment Share on other sites More sharing options...
CP2k Posted July 27, 2003 Report Share Posted July 27, 2003 I have found that D.paradoxa and petiolaris can tolerate lower temps(without going dormant) than many other members of the petiolaris complex. Paradoxa is probably the easiest to grow of all the petiolaris complex dew. Quote Link to comment Share on other sites More sharing options...
AdamH Posted July 27, 2003 Report Share Posted July 27, 2003 Thanks for all the info everyone! I'm sowing the Drosera ordensis today, but I may try to locate plants of D.petiolaris and D.paradoxa as by most accounts these are the easiest / most tolerant species. Incidentally, Allen Lowrie in his book "Carnivorous Plants of Australia - volume 3" mentions that in habitat: "Temperatures are generally high and the average maximum is in the low 30s with a drop of a few degrees during the rainy season. The average minimum temperature is about 17C. Maxima of 45C are often experienced, whereas in winter temperatures as low as 0C sometimes occur on clear nights. In June 1994 I observed ice on the water in buckets early in the morning at Russ Creek on the Mitchell Plateau in the Kimberly. The hottest times are just before and after the wet season." (This is from page 20, in the "Perennial tropical Drosera" chapter). This suggests that sometimes in nature the plants can experience very low (almost freezing) temperatures occasionally - but that perhaps this would be accompanied during the day by a comparatively huge rise to 25 - 40C!! This temperature difference between night and day would probably be very difficult to reproduce in cultivation, which is why we moderate them, but I guess if the temps for your plants get too low, if you make them as high as possible the following day they may survive - a possible survival / emergency tip?! Also, I note the Mitchell Plateau (Kimberly) location he mentions for cold temps is home to Drosera kenneallyi (see page 184 if you have the above book), so maybe this species is also tolerant of temporary lower temperatures? Anyway, thanks again for all the help, I'm going to build a "woolly terrarium"!!! And then try to locate some plants.... P.S. My 200th CP UK forum post!! :mrgreen: Quote Link to comment Share on other sites More sharing options...
Tim Posted July 27, 2003 Report Share Posted July 27, 2003 Matt, I tried and no luck. Dean Cook told me yesterday that the same thing happened to him, although D. falconeri was more difficult that the others. I think anyone in the same situation as me would be wise to try paradoxa first. Quote Link to comment Share on other sites More sharing options...
