This discussion reminds me: does anyone out there grow Typhonium 
diversifolium in the open garden, and if so, what does it require?  I've 
been nursing a bunch of these strange Himalayan aroids in pots for years; 
they seem to have an extraordinarily brief active period, but they're quite 
enchanting when they're up.  I haven't yet tried any in the garden.
