[Arisaema-l] Arisaema griffithii germination protocol?

[aaron floden]

Wattii and other wild collected seeds of Arisaema are available here; http://trillium.no/

I am of no help regarding cold-stratificaiton of those species though.

Hello,
 
I recently received seeds of A. griffithii, and A. griffithii var. pradhanii and would like to know if either of these species require cold stratification. I usually pre-germinate my Arisaema seeds by placing them in moist paper towel, enclosed in zip lock bags, all kept at room temperature. Most species seem to respond well to this treatment, although I have yet to have any luck germinating Arisaema nepenthoides in this manner.
 
I have already bundled the seeds in paper towel, and wonder if the bagged seeds should now be placed in the refrigerator for cold stratification? If so, what amount of time should I allow before returning the packets to room temperature?
 
I would welcome any advice.
 
I am also hunting for seed of A. candidissimum, and A. nepenthoides.
