[Arisaema-l] Arisaema griffithii germination protocol?

[melissa]

Hi Gordon,

I have as yet to germinate any seed of A. griffithii either. I have seen
pictures from England were they self seed and germinate around the parents
quite well.

So maybe there is something to giving the stratification a go. In which case
at least a month in the fridge at around 4 degrees Celsius should get you
some indication.

 

Thanks for the link Aaron.

Have you purchased from this person before?

 

Regards Colin

Wattii and other wild collected seeds of Arisaema are available here;

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.
