Don't know why... I did the usual. Spray some fungicide and forget about them for the winter. I even lost my adult 'Leah Wilkerson' and 'Hurricane Creek White'. Naturally, all most all of the baby unknown hybrids made it. I guess I can trade those if you want quantity over quality.) Half of the survivors I had to salvage what I could and cut away rotting tissue and growth points. Sad day.
I've got a medium-sized 'Red Dragon' for trade for any Sarracenia. Not much but it's all the extra I have.
