I just thought I'd start a thread about fun and interesting Nepenthes observations. Feel free to chime in, and pictures are always appreciated.
First up, and the inspiration for this thread, is that N. rafflesiana, at least for me, is the plant which has its pitchers grow the most after opening. Regularly, a pitcher will grow, inflate, open, then double in size. The guy below was half that size when he opened.
Second, at least some, N. ampullaria have "fuzzy" leaves. I've been making some observations of Nepenthes leaves recently and noticed that it's the only one that I have with a fuzzy coat on its leaves.
Third, when bicals decide to grow they can really grow. This morning, when I left for work, this plant had only the stub you see to the left. Now, somewhat less than 12 hours later, it has a whole new leaf.
That's my contribution for the day. Feel free to join in!
