  Thank you Michael for checking Amazon! 17-21 C does make sense for 
summer soil temp. And I also suspect that cooler winter temperatures 
than 9C are acceptable in situ, if not in Dutch greenhouses -- I would 
guess at least 3 months worth from Lee's Guernsey data.

One further note: I transplanted my few N. sarniensis ('Corusca major', 
as it happens) about a month ago. They were growing in my local clay 
with rather more shade than I'd intended. They had not received any 
intentional supplemental water -- the soil was completely dry. The bulbs 
were firm, large, and scaling nicely, but they did not have extensive 
fleshy roots (at least not compared to the Boophane I inadvertently 
disturbed during the transplant). They produced many leaves last year 
but no flowers. I moved them to a hotter and drier spot, which may have 
been a mistake... We'll see how they respond.

Best,
