Zantedeschia

One small correction to Marieke Mendes' remarks about zantedeschia species:
Z. aethiopica collected from the Eastern Cape is summer-active and
winter-dormant, even if kept above freezing in a cool greenhouse. I have a
clump grown from seed collected near Leopard Falls in the Cathcart district
(thanks, Cameron! :-) ), and it grows and blooms lustily here in summer.

This year I'm leaving it in the garden to test its hardiness ( I did collect
seeds from it first, and will probably retrieve a some tubers before the
deep freeze sets in). Some of the Z. albomaculata from seed I collected in
Lesotho overwintered quite nicely last year in the garden, and bloomed this
summer. I wouldn't claim zone-5 hardiness for these things - we do have
excellent snow cover - but some of them are hardier than people think.
