Re: Amorphophallus bulbifer stories


Albert,

This will certainly not help you unravel your apparent mystery, but I could add
that my A. bulbifer was the first to emerger (from the ground) this year,
some time
in May. The bulbils from last year that I had sown in a container earlier this
spring emerged about a month later. My largest plant has a leaf about 3
feet tall
now, but still has not flowered. How big does this species need to be before it
flowers?

My A. paenifolius emerged in June and the leaf reached 4 feet. This one
also has
not flowered...again same question: how big 'til it blooms?
