A picture would be helpful. But what you're describing doesn't sound like an EE. At a guess I'd say Hippeastrum (Amaryllis). EE's have tubers (think potato, sweet potato, etc.), whereas Hippeastrums are bulbs (think onion, etc.). And Hippeastrums do often come out in colder weather, although I don't know if your cold will be too cold for it or not.

Pat, go to this site: http://www.centralfloridafarms.com/elephantearcare.htm They have lots of good info about aroids.

This is the first year I had to cut all my bananas to the ground I found the younger (smaller diameter) seem to regrow from the center older (lg dia) pup out so it may have something to do with age of the stalk.

As an update, I got some ee's from Michael and plopped them in the ground next to my stream, and within a week or two they had taken off. Now, a month or so later, they've formed a graceful 3 ft. tall or higher ruffle along one side of the stream, with some of the leaves getting at least 1 1/2 feet wide. At least. I also planted some from the grocery store, and they took longer, but have now sprouted and made pretty little ones to fill in between the big ones. Yay! Now- any ideas for contrasting plants to plant in front of them as the next layer of that bank of the stream? Wet and partial to full shade. I'm thinking maybe creeping jenny in between the stems of the ee's.
