There were below freezing temperature for most of the night last night, with a low of 28, although a few places in the garden appear to have stayed warmer.  Some plants suffered damage, some not.  The Shrimp Plants will continue to flower as long as the temperatures stay above the low 20's (℉).  I'm loving the Hairy Roger Cactus.  The photo shows one on a recent misty morning.  The chickadees like to pull off the hairs to line their nests.
