Lachenalis freeze tolerance

Here, various Lachs and also Massonia have been frozen solid in overnight
lows to the mid 20s F and contined growing none the worse for wear.

Silverhill lists all Lachenalia species as hardy to USDA Zone 8. I think
this likely means overnight lows, with the following day's temperatures
above freezing.
