Eduardo,

Spoken like a true Arisaema enthusiast - seeds and plants in the frig,
food in the greenhouse.

Your A. amurense is doing what quite a few Arisaema do. It makes roots
and a tuber the first season
and puts up a shoot the following season. You don't have to refrigerate
it if the winter temperature
will get down to 10C for at least a month. Otherwise, refrigeration is
recommended. In any event,
refrigeration for 2 months and replanting will give you a shoot much
faster. Using a 2 month cold period and a 4 month growing period, one can
compress a season into 6 months giving 2 years growth in one year.
We've brought some Arisaema to bloom in 2 to 3 years using this
technique.

I can't remember which species exhibit the no-shoot behavior regularly,
but a search of the Arisaema-L
archives <http://listserv.surfnet.nl/archives/arisaema-l.html> will lead
you to a lengthy thread on
this subject. There's also some great advice on how moist to keep
Arisaema tubers when refrigerating them. Too moist and they rot, too dry
and they dessicate.
