Zantdeschia hardiness

Keith Ferguson wrote an interesting note in the most recent edition
of the Hardy Plant Society's Journal (Vol. 30, No.1), in which he
named a new cultivar of Zantedeschia aethiopica, 'Glencoe'. It has,
he says, 'leaves 110 - 150cm high, flowers with spathe 15-20 x
12-15cm and held 25 - 35cm above the foliage. It is very vigorous and
very floriferous.' The clone was present in Keith's garden when he
bought the house, in one of the coldest parts of England, and had
apparently been there for at least 18 years, occasionally self-seeding.

It sounds good to me, but is presumably not yet commercially
available in the USA (or the UK for that matter). I could be bribed
to try and twist Keith's arm...
