I'm very interested in trying some different strains of Z. aethiopica. I've
tried it outdoors here in NW Arkansas several times, with plants from several
sources - though I've no idea how different they really were as far as original
provenance - and of course failed miserably each time.

Here the problem seems to be our wildly fluctuating winter and spring
temperatures, just as Jamie describes. Z. aethiopica repeatedly starts into
growth too early, gets zapped when we have a hard frost, and after some number 
of cycles just fades away. All the others stay safely underground until well 
past the danger of any frost and so do well.

I've not tried it in a very wet situation, despite all those pictures I've seen 
of it in habitat standing in water. It's an interesting idea. What depth of 
water will Z. aethiopica tolerate?
