So I got his e-mail address, sent email, and new member responded:
"I have been looking off and on for 2 days!!
I will have to go back to Paradise on Congress to get the name again.
It takes full sun. I have NEVER watered mine after the first two weeks, and it is about 2 feet around and has produced hundreds of babies. The seeds grow easy, and it also grows babies on the flower stalks.
It will get about that big in one season."
So there you have it! I believe I'll keep it in the same pot for the time being. I think "Paradise on Congress" is his name for The Great Outdoors Nursery. I may run over there tomorrow and see if they know what it is.
