This issue has been touched on but I think not yet fully explored.
Zantedeschia aethiopica has a wide range in South Africa, encompassing both
winter and summer rainfall areas.

It seems sensible to me to assume that most importations of Zantedeschia
aethiopica have been from the area around Cape Town, where it is very
common, even growing at the very tip of Cape Point. These winter growers
would certainly be tender in northern Europe, necessitating the glasshouse
culture/underwater techniques to survive.

I have collected seed of Z. aethiopica on the Sani Pass, in Kwa-Zulu-Natal,
a classic summer-rainfall location and source of many hardy plants for UK
gardens. The seedlings are absolutely hardy here and flower in midsummer.

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. If so, it demonstrates the
importance of provenance when selecting South African material for garden
use. (Another plant with similarly wide distribution in SA & reputation for
tenderness is Melianthus major: again, one suspects that most seed has come
from the Western Cape, and one wonders how material from the Drakensberg
would fare.)

The pink-throated form of Z. aethiopica also seems to be entirely hardy
here, and occurs in eastern south Africa somewhere as a wild plant.

Z. albomaculata survives outside here, but is late to emerge, and does not
flower very freely.

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

I'm a bit south of Jane. Here, the Z. a. types are trying to grow
all winter. Every significant frost turns any growth to mush and
so they can seem to be dormant. When frosts stop they recover
quickly and bloom in May-June. Flower vase trivia: To get much
longer cut-flower stems, carefully pull them rather than cut
them.
They do remain evergreen if watered in summer. They look
best in some shade. I like to extend the bloom season and
have them planted in all sorts of conditions. They do do ok in
full sun with no summer watering (and are summer dormant). I
have seen the advise to plant them in water. I have not had
luck planting them more than a few inches below the water line
in my fluctuating winter flooded areas. I will try some more
though. I'd guess they like summer wetland, winter dry
conditions? They do so well here, I am concerned they may
turn out to be invasive and difficult to control someday.

Hi, I received an enquiry about N. tazetta from a reader of PBS, but I deleted inadvertently the email before answering. I am sorry. If you want send me the email again, this time I'll be more careful!

Zantedeschia aethiopica 'Glencoe' is named after Keith and Lorna Ferguson's
garden in Gloucestershire, where there is a huge bed of it - a truly
magnificent sight.

Dear Friends,
Hats off to Jay Yourch and his new Crinum pix. Keep 'em coming.

He is growing, hybridizing and documenting a lot of great
plants and with his friend Alani Davis extending our joy of these
great plants.

If you think Zone 5 or even 6 is too cold, stop and try some.
We grow a bunch in the ground and some do fine in large, but not
enormous, pots. Seeds coming to BX soon.

Thanks to Jay and Alani. Jim W
