Rob-Rah Posted March 8, 2005 Report Share Posted March 8, 2005 Can someone tell me anything about Drosera banksii at all? I have seen a few pictures, and it looks attractive, and I am considering getting seed to try. No-one here seems to have it on their growlist. I know nothing at all about it, except what I read here: http://www.crazyjoe.us/carnivorous/drosera...tralianinfo.htm. I am assuming that as it's northern Australian it will want bright sunshine and steady hot temperatures (maybe like Drosera indica). This is just guess though. If anyone knows more that would be great. Thanks for wisdom in advance. Cheers. Quote Link to comment Share on other sites More sharing options...
JanW Posted March 8, 2005 Report Share Posted March 8, 2005 Hi, I sowed some seed recently and will post pictures of this rarity if they germinate. I don't have spares, don't ask. D. banksii is a lot like the tuberous species but dies back instead of forming a tuber. Its an annual. In my setup the tuberous species grow all year under lights and I hope those plants will do that too. Cheers, Jan Quote Link to comment Share on other sites More sharing options...
Fernando Rivadavia Posted March 8, 2005 Report Share Posted March 8, 2005 Hey Rob, D.banksii is a strange plant that fooled taxonomists for a while. It is strange because it looks like a tuberous Drosera but has no tuber, it is annual and grows in N Australia where no tuberous species are found. It has only recently been identified as an erect member of the petiolaris-complex. Don't know if it's easy to grow, but good luck!! Take Care, Fernando Rivadavia Quote Link to comment Share on other sites More sharing options...
Rob-Rah Posted March 9, 2005 Author Report Share Posted March 9, 2005 How odd, clicking on the link above doesn't seem to work... Anyway, the text from the site is: An Australian sundew that doesn't form a tuber, but completely dies in the dry season and comes back from seed. It's a small erect plant that gets up to 4"(10cm) tall. Blooms white flowers. Will grow continuously if you don't allow it to dry out. Allen Lowrie wrote that it is closely related to D. subtilis, however D. banksii has pubescent flower stems and flowers have 5 petals, 5 styles. D. banksii also will continue to grow until the dry season, whereas D. subtilis will only grow through the early weeks of the wet season. It's part of petiolaris?? I might have a go I think. I don't grow any of the others of the group, but am setting up a high light, high temp tank at the moment that might do. Jan, are you also trying D. subtilis?

BobZ Posted March 9, 2005 Report Share Posted March 9, 2005 There are some nice photos of D. banksii at http://www.asahi-net.or.jp/~ze9h-wkby/d-banksi.htm Quote Link to comment Share on other sites More sharing options...
Sean Spence Posted March 9, 2005 Report Share Posted March 9, 2005 I grew it once from seed many years ago. It germinated well and grew for around a year before flowering and dying without producing any seeds. As with the other members of the petiolaris group keep it extremely warm- hot. To be honest it wasn't the most attractive plant I've ever seen and have never felt compelled to try it since. Quote Link to comment Share on other sites More sharing options...
JanW Posted March 9, 2005 Report Share Posted March 9, 2005 I grew it once from seed many years ago. It germinated well and grew for around a year before flowering and dying without producing any seeds. I will do my best and play bee... @Rob: No I have only D. banksii and some interesting variants of D. indica from the Northern Territories. Perhaps those will get more common the next years as there are some some around now. Cheers, Jan Quote Link to comment Share on other sites More sharing options...
Sean Spence Posted March 9, 2005 Report Share Posted March 9, 2005 note- should be the Northern Territory rather than Northern Territories- there's only one of them . It is similar to a state such as Queensland or Western Australia but hasn't been recognised as one due to the low population. Good luck with the seed. It should germinate and grow quite easily, as with the D. indica. Quote Link to comment Share on other sites More sharing options...
Andreas Fleischmann Posted March 12, 2005 Report Share Posted March 12, 2005 Hello! I grow D.banksii since about 5 years now, actually the plants are annuals and you have to regrow them from seed each year. Seed production under my growing conditions was good, although not each flower did produce seed, despite hand-pollinating them. I grow my plants in a hot greenhouse, same conditions as for members of the petiolaris-complex or for D.indica. BTW, in both D.indica as well as in D.banksii (and D.subtilis, which I grew from seeds last year for the first time. Unfortunately, I did not get this one flowering and thus I lost it again ), I had timed mass germintation (about 90-100%) with the following method: I sow the fresh seeds on moist substrate imedeately when ripened (peat:fine white quartz sand:loam = 2:2:1), keep them wet for several weeks (no germination at all!), and then let them dry out and neglect them for about 6 months. In late winter (January/February), I keep the pots moist again, and within about 2 weeks, there are first signs of germination. It's quite like growing tuberous Drosera, just timed the other way round! ;-) Another trick to avoid sowing these annual tropicals each season is to take cuttings (I just cut of the top, about 1-2cm in D.banksii and 3-4 cm in bigger D.indica-forms, tip the base of the cutting into rooting hormone powder and stick the cuttings into wet peat-sphagnum mix under growlights indoors (more than 12 hrs of light, otherways they will dy back as I experienced). Both the cutting and the mother plant will restart growth (the cutting from the top, the headless mother plant from lateral dormant buds), thus this is a way of slowly propagating this species, too. All the best, Andreas Quote Link to comment Share on other sites More sharing options...
Binataboy Posted March 12, 2005 Report Share Posted March 12, 2005 Thanks for that bit of info Andreas, it is very interesting about doing cuttings of indica, do you know if this works for other "indica" plants like hartmeyerorum?

JanW Posted March 13, 2005 Report Share Posted March 13, 2005 It worked for me with my D. indica, too. I took only a 1 cm cutting when the plant was dying back and it worked. Cheers, Jan Quote Link to comment Share on other sites More sharing options...
Andreas Fleischmann Posted March 15, 2005 Report Share Posted March 15, 2005 Dear George, Yes, it works great for D.hartmeyerorum, too. There's one German grower who was offering this one commercially, and he propagated all these D.hartmeyerorum from cuttings. Andreas Quote Link to comment Share on other sites More sharing options...
Tim Posted March 15, 2005 Report Share Posted March 15, 2005 Forbes does it also from cuttings, but as he told me, and as I found out, the cuttings are more "wimpish" than seed grown plants. Still worth it, though! Quote Link to comment Share on other sites More sharing options...
Rob-Rah Posted August 1, 2005 Author Report Share Posted August 1, 2005 Jan, any joy with your D. banksii seeds? I am just about to plant mine - I will try the drying out method if nothing has sprouted within a month or so. I guess as I am growing under strong lights and with artificial heat that the seasons are irrelevant to me for the petiolaris group. Is this a sensible time of year to be planting Byblis seeds? I recall a post by Stefan advocating autumn sowings... Quote Link to comment Share on other sites More sharing options...

It has only recently been identified as an erect member of the petiolaris-complex. Don't know if it's easy to grow, but good luck!! I missed this thread the 1st time around (Thanks Rob!!). I'm curious what prompted the classification into section Lasiocephala .... Quote Link to comment Share on other sites More sharing options...
Greg Allan Posted September 5, 2006 Report Share Posted September 5, 2006 Hi Rob, Which Byblis species are you thinking of sowing? I sowed a handful of B lamellata around this time last year, and I now have a large adult plant that has been flowering for several months. Cheers, Quote Link to comment Share on other sites More sharing options...
Rob-Rah Posted September 5, 2006 Author Report Share Posted September 5, 2006 B. gigantea / lamellata types - but that was last August! lol However, I do have some seeds in storage I could do with planting I suppose. I also have the GA3 ready and waiting to mix up. I seem to be in a sort of inertia about such things recently. Do you sow direct onto the pot destined for the adut plant, or into trays/small pots and prick out? Quote Link to comment Share on other sites More sharing options...

Petiolarissean Posted October 13, 2006 Report Share Posted October 13, 2006 I will tell you the story that Allen told me.He asked me one day if I would hybrid it with a Petiolaris Complex plant.When I asked him why?He stated it was the plant most related to the Petiolaris Complex of plants.He said it was related,not part of the complex.I asked him where he obtained this information.He said the Germans.Hope this helps!Petiolarissean Quote Link to comment Share on other sites More sharing options...
Rob-Rah Posted February 21, 2007 Author Report Share Posted February 21, 2007 Well, for what it's worth, no germination of D. banksii or D. subtilis after almost two years. I have thrown the pots out today. Varied the wetness, heat of 20-35C, bright light all the time. Nothing :-( Oh well. At least I have room for some Byblis pots now. lol Quote Link to comment Share on other sites More sharing options...
