Just for fun (and to validate the effectiveness of the pre-made sterilization solution), I tried some of the Drosera capensis x aliciae seeds from @Lloyd Gordon and it worked! Lloyd has given me the seeds long long time ago, and I have tried some on peat but nothing sprouted. I'm surprised that the seeds are still viable and worked!
Drosera capensis x aliciae, sterilized and planted on March 28th
Drosera venusta, seeds from @stevebradford, sterilized and planted on April 6th
