I forgot some Drosophyllum seedlings last December outside. -15 for several nights and finally thawing after two weeks. I have them growing on floating islands with only a few centimeters of substrate.
After thawing I put them in my frost-free studio. Light level in winter is quite low. I put some aluminum foil behind to increase the light.
Now they start again to grow.
First picture is after the thawing, second from today.
