Re: I need information on Amorphophallus Paeonifolius -any experts out there?

Ty didn't say where he was, but he said he was expecting his first frost 
in a week. That's enough info for me - his plants are sitting in the 
cold and the potting mix is probably wet. For me that has been fatal to 
almost every species.  If they were in dry mix they might be OK, but in 
my experience being damp and cold is an excellent way to guarantee a 
dead paeoniifolius.  The plant itself may look healthy and the tuber 
might feel firm, but by springtime it's likely to be shriveled and 
dead.  Just my own experiences...
