byblis Posted April 13, 2006 Report Share Posted April 13, 2006 Hi all, I was asked for growing tips for both species. Here is just what I do with it. Plants grow and survive, sometimes produce plantlets but didnot flower so far. (D. stenopetala flowered in vitro one day): Substrate: Pure peat, I have tried mixes with perlite, sand, Vermicullite but find as major disadvantage the groth of moss, algae and so on Light: As much as you can give them, I found D. arcturi at the edge of a skiing rope/lane in N.Z. (Southern Island) agrowing in fully sun light at high elevation with much UV-light Climate: If possible cool mountain climate, plants seem to suffer if it is too hot during the summer especially if the night temps donot drop down Temperatures: Winter resting periode: 14°C days down to 6-8°C night temps, D. arcturi is fully hardy and I have kept it in my outdoor bog with temps around -20°C. The problem is that plants get overgrown by sphagnum and will die of it; D. stenopetala was not hardy so far and died outside, it should be hardy in British "winters" :-)) Summer: Continental European aclimate, temps as high as 35°C are tolerated if night temps are much lower Hope this helps!

Guest Aidan Posted April 13, 2006 Report Share Posted April 13, 2006 Stefan - Thanks for the advice. Quote Link to comment Share on other sites More sharing options...
Chloroplastik Posted April 13, 2006 Report Share Posted April 13, 2006 Thanks Stefan. I grow stenopetala from Stewart Island outdoor (Brittany - West part of France) without any problem. Plants from this location may be the most hardy (?). D. arcturi seems to grow mainly in black peat in the wild. Quote Link to comment Share on other sites More sharing options...
Sean Spence Posted April 14, 2006 Report Share Posted April 14, 2006 D. arcturi seems to grow mainly in black peat in the wild. Wherever I have seen D. arcturi growing in the wild it has been found in 100% live sphagnum. Quote Link to comment Share on other sites More sharing options...
yves Posted April 14, 2006 Report Share Posted April 14, 2006 Hi everybody I agree with Sean, all the D. arcturi I have seen in Tasmania were growing in pure sphagnum. I grow both species in pure sphagnum, as Byblis, they rarely produce flowers, in my case D. stenopetala has flowered one time. Temps are 5-10°C during winter and can reach 35°C in summer days but never over 25°C during nights. In my case, high temps induce the formation of winter buds. In mid august plants begin their resting period. Yves Quote Link to comment Share on other sites More sharing options...
Chloroplastik Posted April 14, 2006 Report Share Posted April 14, 2006 Well, I've never been to New Zealand and Australia but I've seen many pictures of D. arcturi growing in the wild with typical black peat flore. An example here: http://www.sarracenia.com/photos/drosera/darct01.jpg You can also have a look to Lowrie's Carnivorous Plants of Australia volume 3 p139, pictures was taken in black peat bog(s). I can also read p 136 : "HABITAT: Grows in sphagnum bogs in the alpine hearthlands and in black peat along the margins of small streamlets." Yves, for stenopetala you use live or dead sphagnum?

Sean Spence Posted April 14, 2006 Report Share Posted April 14, 2006 Just commenting on my own experiences in the wild. I didn't say that they don't grow in peaty soils, just that the ones I have seen have always been in pure sphagnum. Quote Link to comment Share on other sites More sharing options...
sundewmatt Posted April 14, 2006 Report Share Posted April 14, 2006 I've found fertilizer may help some plants which rarely flower. Give it a try.... Quote Link to comment Share on other sites More sharing options...
