Greg Allan Posted July 28, 2010 Report Share Posted July 28, 2010 I have a greenhouse that is in full sun all day in summer and full sun for a few hours per day in winter. It is heated to approx 5 deg minimum in winter. Will tuberous Drosera and S. American Drosera be OK in there during British winters without additional lighting? Last winter, the light levels proved sufficient for Drosophyllum- I overwintered 5 plants with no losses, as well as a number of South African species (e.g. capensis, collinsiae, regia, venusta, slackii, etc) and a couple of pygmy species (e.g. scorpiodes, pulchella, occidentalis, sewelliae). Does anyone have any experience with tuberous/S Americans in winter in the UK or at other northern latitudes? Cheers, Greg Quote Link to comment Share on other sites More sharing options...
Zlatokrt Posted July 28, 2010 Report Share Posted July 28, 2010 I cannot say much about tuberous drosera, but i think, that South American sundews should survive there. They won`t grow fast, but they should survive OK. I had my collection of these sundews in 7 - 10 °C during last winter and i think that they would survive even lower temps.

Simon Eyre Posted July 29, 2010 Report Share Posted July 29, 2010 Hi Although we are a bit warmer here, I grow my tuberous sundews outside. We go down about as low as 3 or 4 degrees and only get a upto about half a dozen frosts a year and they do fine. So I would have thought that they should do well in there. We had one of our heavier frosts a couple of days ago and they are still growing more than happily enough. Cheers Simon Quote Link to comment Share on other sites More sharing options...
Sean Spence Posted July 29, 2010 Report Share Posted July 29, 2010 The temps will definitely be fine, but I believe that Greg was more interested in whether the lighting will be sufficient? My tuberous Drosera are all grown fully exposed through necessity this season and have easily coped with temps down to 0C plus at least 6 frosts so far. Sorry that I can't answer the lighting question Greg. My plants don't get full sun all day at the moment- probably 4-5 hours around midday. They are all doing perfectly so far.

Simon Eyre Posted July 29, 2010 Report Share Posted July 29, 2010 Sorry I misread that bit. Mine get bright sun from about 10 am until about 3 pm during winter. The rest of the day their position is fairly shaded. They are doing really well, so I would have thought a greenhouse in a British winter should be ok.

Nigel H-C Posted July 30, 2010 Report Share Posted July 30, 2010 Hi Greg, I used to light my South Americans over winter, but didn't last year and did lose a few. There may however have been other factors at play though! I don't give any extra light to the tuberous species and they all seem to colour well with the few hours of sun we get more than enough to sustain good growth.

Greg Allan Posted August 2, 2010 Author Report Share Posted August 2, 2010 Thanks for the advice. Much appreciated. Greg Quote Link to comment Share on other sites More sharing options...
MFS Posted August 3, 2010 Report Share Posted August 3, 2010 Frost-wise, mine have got about 20 or 25 this year. Even this one, and you can see how well it grows. Light wise, they are in full sun with a white wall behind them. Quote Link to comment Share on other sites More sharing options...
Tim Caldwell Posted August 3, 2010 Report Share Posted August 3, 2010 (edited) Hi Miguel, Your 'Typical Victorian Form' does indeed look a lot like the ones I see all around Melbourne - but also for that matter like the ones I've seen around Launceston in Tassie, near where you live :-) The mainland 'D. whitakeri' from west of Victoria look to me (and I'm no expert), like a completely different species. Around Melbourne, the main variation I've noticed is just the degree to which they turn red in strong sunlight - some just don't, and some readily do. It's one of the several drosera species that grew next to my childhood home, and all I can say is that it isn't called the 'Scented Sundew' for nothing - don't those big flowers smell fantastic ?! In a really good year they turn a stroll through the local park into a dream. Cheers, Tim Edited August 3, 2010 by Tim Caldwell Quote Link to comment Share on other sites More sharing options...
gardenofeden Posted August 3, 2010 Report Share Posted August 3, 2010 Greg, temps wise you are probably OK as others have said. Light-wise I am not so sure, I struggle up here in Yorkshire with anything but the easiest species (peltata, auriculata) which I think is down to the much lower light levels here compared with the south of England, they cannot put on enough growth to get through dormancy. You may just be Ok there in the Midlands...only one way to find out! Quote Link to comment Share on other sites More sharing options...
