Zantedeschia hardiness

Mulling over it, I came to the thought some time ago, that the generally
reliably hardy clones in the UK, e.g. the old but unspecial 'Crowborough'
and the recently named 'Glencoe', are probably from the summer-rainfall
area, though this is impossible to prove.
There is is a small town close to Dundee called Glecoe in the north western
part of the KwaZulu Natal province, so if this clone is named after the
place of collection, it is from a summer rainfall area, with probably very
cold winters.
Hope this helps
