I thought I'd start a thread for pictures and discussion of UV fluorescence in CPs. I get the impression that it's not a very well-known phenomenon, and I'd like to change that!
I'll start with a fantastic picture of N. "Triffid" I took last night:
And one of my random hybrid from April (possibly identified as N. ventricosa x angasanensis.) The pitchers are old and dying back, but they had lots of super thick nectar on them to fluoresce.
