Arisaema Germination (was: Soaking colchicum seeds)

Are you referring to both the Asian and North American Arisaema species? 
I've had A. sikokianum germinate for me at 70 F (20 C) without any
pretreatment at cold temperatures.  I've heard, however, that A. triphyllum
is difficult to get to germinate.  (I haven't tried, though.)
Apologies to Rodger Whitlock for continuing the germination thread, but I
am not incurious about the factors that trigger seed germination. 
(Something about meeting Norm Deno at an impressionable age, I guess.)
