Hi Vincent,
Well, I am a total novice, but for me this sounds about right.  On rare occassion they will decide to go totally dormant, but for me it is not very often....maybe once every 2-3 years or even longer.  In my case I keep them nice and warm on a heat mat in their pots and maybe once every 2 weeks or so give them some water when dormant......never wet like in the growing season, but enough to keep them from being bone-dry......I guess I would think of them like one of the pseudo-evergreen Amorphs.....like A. titanum.....just  a bit of water to keep them happy until they reemerge from dormancy.  I typiucally do not repot until I see some new growth emerging and then repot...the more compacted soil from the past 2-3 years will keep them barely damp for a longer period of time compared to fresh, light soil....or so my thinking goes!!  I've had them stay dormant for just a month or so all the way to one of mine that is just now emerging after 5 months of dormancy (this is a no ID from Brasil).  As I said, this works for me here in zone 6 after some trial and serious error, but others with more experience than  me can hopefully provide better info.  By the way, I also find that after a dormancy like this is when you see a big difference in the size of the petioles produced, but maybe that is just mine in my conditions.
I've managed to have a Dracontium prancei now bloom for me as well so I'll try to take pics and post in the near future......2 Dracontium bloom in one season.....the most exciting aroid season for me in a long time :o)

Subject: [Aroid-l] Dracontium amazonense going dormant?

I ahve a Dracontium amazonense going dormant now. Ive kept is wet and warmer then outside. It started by slowly loosing leaves. finally only one was left and the last one stayed there for about another month. now it is starting to turn yellow and the stem is softening like the others did before falling off.

I also have several offsets in the pot. Non of the offsets ever sprouted but the did grow roots and get larger in size. After checking the offsets, I see that they are dormant also because their roots are gone. I have fertilized them the whole time theyve been growing, almost 2 years now.

Can anyone tell me what is going on here? are they going to sleep or something else? If they are resting, how long will they rest?how should I store them?
