I hope you're right about being "in the clear," Cindy !
"The redbud may be one of those that are late breaking dormancy trying to avoid that. " Donald, I've been wondering about that, too... since the flowers come before the leaves, it would make sense if it was just generally later to avoid the blossoms getting frozen.
I'm not too keen on the winter temps here -- but I'd rather deal with that than with the heat in the south!
(No wonder so many people live in the south in the winter and the north in the summer...)
