I received a request for information that has intrigued me.  I am not  
able to answer, but perhaps one of you has an idea.  I didn't think  
Amorphophallus would stand the winter in Ohio.  Isn't it semi-tropical?

Here is the query:

About 15 years ago we received 1 bulb of the Amorphohallus rivieri. At  
last count we have 75 plants growing around our property. These 75  
have not been planted or in any way encouraged. They just sprout where  
ever they choose and surprise us in out of the way locations far from  
anyother clumps. If they are a bulb, how are they spreading? In all  
these years we have only had one plant produce seed. Each spring there  
will be only one or two that bloom, for which I am very thankful!! I  
have done internet searches and am unable to find an answer to the  
abundant proliferation of this unique plant on our property. We live  
in Cincinnati, OH.
