The different stages of growth certainly yield distinctly different looking pitchers.
The juvenile, intermediate, and adult pitchers have their own unique shapes and coloring, complete with the intermediate's nectaries under the lid, that resemble the bane in every teenager's social nightmare ...acne. (Although today that social nightmare might be losing their phone)
How long have you been growing this plant for Corky?
Hi dvg,got some cuttings of n.copelandii a few years ago , one of the easy species I find , bet it would grow on a windowsill but this ones under a Flo light,think I'd rather acne than losing my phone ,first world problems 🙂
A first for me ,a hamata upper pitcher far from a perfect pitcher as the lid shrunk and a couple of teeth didn't form properly but I'm not surprised as humidity gets as low as 30% , larger than I was expecting the newest from n.palawanensis
Been doing a bit of well needed mucking out in nepenthes corner, took a couple of pics whilst hacking back dead pitchers and tangled mess n.sibuyanensis x burkei a promising n.veitchii And my three seed grown n.palawanensis, first pic a tubby one then slim then stripy, done well I reckon to have three different looking plants ,it will be interesting to see them progress, slowly
Been ages since this n.robcantleyi has formed a nice pitcher without a shrunken lid ,hope it's on the road to recovery, needed to repot it and then it went moody and before I knew it a couple of years had past,but that's what growing these plants is like for me and my terrible conditions .
I shall update with pics as the pitcher darkens , well spotted, it's the donald, big head and little hands, starts nodding his head when the lights come on , a present from a friend and how grateful I was
