Chimaera Posted April 30, 2018 Report Share Posted April 30, 2018 Just started collecting a few carnivores, and looking for suitable plants for an unheated greenhouse (in southern England), it seems that a there is variable advice about the hardness of some species. As we (in UK and some of northern Europe at least) have just had an exceptional cold snap late in the year, it would be interesting to see what survived or otherwise in unheated greenhouses or outside this winter. I was surprised that a D. capensis survived being frozen solid (even iff all the top growth died off). Quote Link to comment Share on other sites More sharing options...
ada Posted April 30, 2018 Report Share Posted April 30, 2018 All mine survived in an unheated greenhouse,again for the 27th year! It never gets cold in London,does it. I have a few for sale that are tough as old boots take a look in the sales area Quote Link to comment Share on other sites More sharing options...
linuxman Posted April 30, 2018 Report Share Posted April 30, 2018 There's been no problem this year even with the cold snap. All my sarracenia have survived as have the drosera though the exposed leaves died off like yours. I am still waiting for 2 D. regia which were in small pots.I have cephs that have survived being in the g/h all winter as well. YMMV.

Chimaera Posted April 30, 2018 Author Report Share Posted April 30, 2018 Just been thinking about why subtropical Drosera and Serracenia would evolve to be so Winter hardy. I would guess that it is because they had to survive the last ice age (too recent for much speciation since), Most animals and plants could survive by moving with the climate belts away from the poles, but increased aridity would have been an additional problem for carnivores. So for Serracenia whilst southern Florida stayed warm, it also got very arid and no good the bog plants, so bog specialists were restricted to northern Florida and the Gulf Coast where winters were probably far colder than now. So even species that now never see a frost in the wild would have only survived by being frost hardy. The same could be true with S African Drosera; whilst the Cape area got colder, expanding deserts and savannah to the North would have trapped the Drosera in a far colder area than now, so only the hardy survived.

jasperD Posted April 30, 2018 Report Share Posted April 30, 2018 I've lost 2 dionaeas this winter in my mini bog and I'm still not sure about a third one. My three sarracenias outside survived all (leucophylla, psittacina and a hybrid with leucophylla and rubra) The lowest temperature they had to cope with was around -10°C.

Dunc Posted May 3, 2018 Report Share Posted May 3, 2018 No losses due to cold this winter. Greenhouse kept 0°C or above apart from one night but also have many sarracenia outside inc leuco, minor, flava, darlingtonia, etc. They're a few weeks behind those in the greenhouse.

Keith Posted May 3, 2018 Report Share Posted May 3, 2018 Same here Dunc. Outside planter is three/four weeks behind. Poly tunnel, all survived to -8 and full of life now. Includes Sarracenia, Flytraps and sundews. Quote Link to comment Share on other sites More sharing options...
Blocky71 Posted May 3, 2018 Report Share Posted May 3, 2018 The sarras and vft's coped ok but my whole collection of ceph's took a massive hit and have completely died back . Time will tell if any recover, I'm hopeful of the bigger plants but I had a lot of young seedlings and pullings that I'm not expecting to recover. Two nights of minus 11 did the damage.....

MarkB Posted May 9, 2018 Report Share Posted May 9, 2018 Lost a couple plants this year in west wales. We had temps as low as -15c and with the wind factor this made for some really cold temperatures. Sarracenia's all survived outside but several of my fly traps and sundews crooked it and they were inside an unheated greenhouse. I also lost a drosera regia that i had been growing from seed the last few years. Quote Link to comment Share on other sites More sharing options...
Blocky71 Posted May 9, 2018 Report Share Posted May 9, 2018 Gutting mate isn't it, no signs of life from my ceph's yet..... some of them were self sown seeds from 2011.... Quote Link to comment Share on other sites More sharing options...
manders Posted May 9, 2018 Report Share Posted May 9, 2018 I lost some UK droseras, anglica, rotundifolia, beleziana and intermedia as they were exposed to the wind. Some of the same species survived that were frozen solid. Also some dionaes, binatas and capensis survived outside. We got to about -5 for a few days.

ada Posted May 11, 2018 Report Share Posted May 11, 2018 Minus 6 to minus 8 is regular now,the lowest temperature was minus 16 in a really bad winter about 2010, all my plants survived that,that are growing now. but i did lose over 70 plants that winter.

Bluedog0628 Posted May 11, 2018 Report Share Posted May 11, 2018 I have lost 1 Drosera binata... At the start of winter, there were 3 plant in the pot, 2 of them came back from the roots, the third one is still missing (I'm hoping it might still reappear but it seems unlikely now). They were in a cold frame with the rest of my temperate plants (Sarracenia, Darlingtonia, VFT). Apart from that, my plants are growing well.

carambola Posted May 11, 2018 Report Share Posted May 11, 2018 Don't lose hope just yet! I thought I'd lost a fairly large binata this winter (I don't have a greenhouse or anything, so simply leave everything outdoors, admittedly the climate here is ever so slightly warmer), but just a few days ago a small bump has started growing from the side. It certainly must have suffered more than the other plants which all have several leaves unfurling or fully unfurled by now, but it survived!
