I have two bulbifer doing exactly the same thing. In fact, A.
bulbifer has always behaved like this for me. It is about as seasonal as
konjac, but leaves only last about 2 months before being replaced. My
bulbifer produce two leaves in succession each season. Sometimes the
original dies, sometimes it dosen't. I rest the bulb in october just like
the knojac. Of course, my bulbifer are still too small to flower yet.
Perhaps mature specimens behave differently. Finally, I find that
Amorphophallus in general need full sunlight to reach their maximum size.

In my cultivation smaller specimens of Amorphophallus bulbifer
usually set up a couple of leaves (2 to 5) one eafter each other for
about 5 months before they finally go dormant (if not growing all year
round, which is not uncommon in this species). Adult specimens
show a strict dormancy and produce only one leaf in a single growing
cycle.
