Dear Steve M (and Ken M) and all; Having been putting in a plug for the Aril Irises lately, I should add one for the International Aroid Society. They have an excellent web presence too and include a page devoted to Hardy Aroids. This page ( http://www.aroid.org/horticulture/hardy.html ) includes this info on our topic Zantedeschia - 8 spp. Zantedeschia aethiopica and cvs.(Zone 7a Raleigh, NC) 0F Zantedeschia albomaculata (Zone 5b Kansas City, MO) -10F Zantedeschia elliottiana (Zone 7a Raleigh, NC)9F Zantedeschia pentlandii (Zone 7a Raleigh, NC) 9F Zantedeschia rehmannii (Zone 6 Springdale, AR) 5F Zantedeschia 'Black Eyed Beauty' (Zone 7a Raleigh, NC) Zantedeschia 'Cameo' (Zone 7a Raleigh, NC) Zantedeschia 'Flame' (Zone 6 Springdale, AR) 5F Zantedeschia 'Crystal Blush' (Zone 7a Raleigh, NC) Zantedeschia 'Crystal Glow' (Zone 7a Raleigh, NC) Zantedeschia 'Galaxy' (Zone 7a Raleigh, NC) Zantedeschia 'Hybrid Yellow' (Zone 7a Raleigh, NC) Zantedeschia 'Midnight Eclipse' (Zone 7a Raleigh, NC) Zantedeschia 'Pink Pacific' (Zone 7a Raleigh, NC) Zantedeschia 'Pink Persuasion' (Zone 7a Raleigh, NC) Zantedeschia 'Pot of Gold' (Zone 7a Raleigh, NC) I bet the data from Kansas City and Springdale comes from Steve and me, while Raleigh info is from Tony Avent.
