Jim McK.,

I have two Zantedeschia in the ground outdoors year round -- and as for the 
Hymenocallis liriosme, these are very close to my greenhouse walls.  One of 
them, Z. 'Green Goddess', survives right up against the wall, but does not 
bloom.

The other, Z. 'Black Pearl', survives and blooms each summer.

'Green Goddess' is a form of aethiopica, and might be expected to be 
tender.  A different form of aethiopica, from mountains in the Eastern Cape 
Province, I had hoped would be hardy.  I never got it tested properly here.

'Black Peal' is one of the hybrids with rehmannii genes in it, and 
rehmannii is probably going to be the hardiest of the genus.  Unfortunately 
I do not have any rehmannii anymore.  We would need seed from wild 
populations from the coldest parts of its range to hope for zone 6 or 5 
hardiness, I would expect.
