Hello, I have a new cephalotus. It was actually quite healthy when I got it. I put it in total shade and it's potted in peat and some kind of inorganic material which I believe is called diatome or something. I noticed that in 3 days, some pitchers are vrown! They were grren a few days ago... erm, do cephalotus pitchers last so short or is there somethg wrong?
