The vines are about 20' long and the tops of the vines emerge into full tropical sun. I've tried grafting on leaves from flowering N. mirabilils to encourage a hormone avalanche. Different fertilisers don't seem to work either. the plants are outdoors and the pitchers are full of prey.
I know that in the wild N. ampullaria sometimes flowers when it reaches a much smaller size than these guys. Has anyone ever seen a flower on N. ampullaria in cultivation and if so, how was it done?
