After two nights of 25 degrees, and yesterday's day temp just clearing the freezing mark, ours here don't look quite so perky. The ground was actually solid from cold again this morning, and the planting mix and water jugs in the Springhouse were frozen, too. A few extra Keckiella cordifolia seedlings left out there seem to be the only survivors so far. I'm not sure how though...their pot of soil is a frozen block.
