  Amorphophallus albus dormancy?
From: ken at spatulacity.com on 2004.03.18 at 17:52:39(11297)
I had two young tubers (not bulbils) of Amorphophallus albus that started
growth quite late in 2003. We had a nasty, cold spring in New England and
all the amorphs were slow. When fall arrived I was afraid they hadn't had
enough growth time, so I took them inside under artificial light.

One of them has just gone dormant, leaf collapsed, the tuber is healthy
although not much larger than last year, I don't think. The second plant
still has its leaf! Will I be able to coax the one that just went dormant
back into growth? The IAS web site's Amorph cultural page says the
after-leaf dormant "period may take 3 to 7 months." I hate to try to put
the plant on my time schedule, but having it perpetually growing during the
winter wouldn't be my first choice!

Is there an Amorphophallus alarm clock that I can use to wake this guy up
when the rest of my plants are starting to grow?

usually Amorphs do not respond to forcing although gradual adaptation to the
seasons of the place of imprisonment does occur but may take several years.
You could experiment with storing the tuber cold (as in 15 C) and see if
this will shorten the dormancy as it does in Caladium commercial cultivation
(up to three growing seasons in one year can be achieved). It's experimtal
but somebody must be the guineapig (did I spell this correctly?)..........
