Question
It seems that my Nepenthes produce more pitchers on the side away from the window. They are in a south window east of
San Diego. Have you seen this?

Answer
Hi Dave,

This is very common.  Nepenthes often produce their pitchers away from the sun.  The pitchers themselves have only a small amount of chlorophyll in them, so they don't photosynthesize that much.

Good Growing!
