Ive noticed on some of my plants the pitchers are all facing the same exact direction, regardless of the position of the leaf theyre attached to. Some have tendrils that make journies across their pots just to make sure they inflate right next to several other pitchers (see my N. burkei a few months ago, was only inflating pitchers in one corner of the pot.) One seems to only inflate pitchers facing away from the sun.
So out of curiosity, what factors (if any) control the direction a pitcher will inflate/face in. Is it just entirely random?
