Thanks so much, Rick! We did seem to have a very brief, and fairly warm Fall. Almost like we went from Summer into Winter overnight!
Yes, the tree is young. As a matter of fact, I found it growing in a flower bed about 6 or 7 years ago. Apparently planted by a squirrel or bird. It was just about 6" tall when I found it, and dug it up, put it into a pot, and kept it in a container until this last year, when I found a spot in the yard for it. Maybe the phenomenon that you spoke of is true to Redbud's as well. We'll wait and see.
Since posting my question, most of the leaves have fallen…It did seem quite strange that the leaves changed from green to yellow overnight…The same night that it was hit by the freeze. Your right only time will tell if it suffered any damage. I'll be keeping my fingers crossed in hopes that it didn't!
