While repotting the red Ampullaria, I noticed a tiny white pitcher protruding from underneath the moss.

I carefully dug out the the rest of the stem to reveal a nice batch of albino pitchers! The most easiest way to inhibit node growth is to bury the stem in a couple of inches of moss. Not the fastest but it has worked on a couple of my nepenthes. Unfortunately these pitchers will soon turn to shades of red with the exposure of sun. Interesting way to uncover albino pitchers!
