After the mean cold spell we just went through, I was looking to see if any of the clay pots cracked and how the daylilies looked after having a day to thaw out. The pots and plants seem to have survived. Variable appearances for the plants though.
'Fritz Schroer' suffered the most, but there are 2-3 others that suffered nearly as bad.
'Grey Witch' looks really good. I'm not saying it came out the best, but it's close and it and 'Fritz Schroer' were about at the same stage of growth. There was an even, gradual change from worst to best between these two examples.
And for a control plant, here is 'Coral Crab' which is in a plastic container. Plastic does not have the insulating properties of a clay pot (don't ask how I learned) and the pot, though large, isn't quite as large. So it, along with all those in plastic or smaller diameter pots, spent more than a week inside the garage. It's the first time it was inside this winter. Really, it just managed to grow a bit taller than 'Grey Witch' and they were nearly identical in growth before the weather system arrived.
Some of those that had strong evergreen type fans may get trimmed back in a day or two, but I'm not seeing anything that I don't think will survive and grow. Those brought inside may have a week or so head start on those left out. Eventually, those I keep around will be in containers that aren't brought in, but I wasn't willing to chance it this time. They've certainly managed all the previous spells this winter without a hiccup, but they weren't actively growing then either.
