Whew!
As of today, I'm still getting spouts in my winter sowing containers. I was a bit concerned when I picked one up this morning to find it board-stiff from cold, but one of the newbies, Slipper Flower (Calceolaria mexicana), is an annual, so I'm guessing that the rest will probably be okay, too. I just checked a few containers today; I can't do much with them anyway until this cold snap has passed.
