Hello Jim.
It sounds like Leo may be able to grow his Calostemma in a way similar to
his Hymenocallis: in large pots sitting in 3-4 inches of water in his pond.
The main difference is that he would have to remove the pots and store them
dry for the summer.  Do you think this would work?
What are typical day and night temperatures during the growing season for
Calostemma?  I have a few seedlings (C. lutea), and they seem to grow as
long as I keep them watered.  I'm growing them indoors, under lights, for
now, so they don't see much seasonal variation.
