I had cuphea David Verity in a pot last year, and it sat on the patio all winter. I pruned the dried branches down a month ago, and when I went to tip out the pot today, there were shoots coming up! This is a nice surprise,and these plants will probably be good candidates for overwintering under mulch/leaf bags.
