The forecast says 30° for both Thursday and Friday night. One good thing came out of last winter's extreme cold. I know more about how cold-hardy my plants are, and won't do as much to protect plants this year. And for the most part, if it can't take mild freezes, I don't want it anyway. Tough love! And the weather last winter/early spring somehow brought up quite a few of the plants I've recently decided is called Sweet Everlasting. I've still got American Lady caterpillars on these plants...in late November! I brought in two more of the caterpillars, however...don't know if they'd freeze out there, but I'll protect them anyway.
