Re: Dracontium amazonense going dormant?

Hi Vincent


It’s a common misconception that the Amazon (indeed much of the tropics) is bathed in rain. Many tropical areas, including the Amazon, have a marked dry season and often a significant proportion of the trees in these regions will be semi deciduous or even deciduous, and a marked proportion of the herbaceous flora will follow suite. The tuber in Dracontium is there to enable to plant to pass through a leafless resting phase.


Very best

Another question. Why would they go dormant if kept warm and wet? this spp is from the amazon.

I refuse to participate in the in the recession.

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?
