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.
I receiveda ope of voluteer DV from Ward yesterday. He is zone 7, awfully so am I nw. Anyway, I think his we're seedlings, ur you'll ace o see what he sys. Great plant that you won't have to replace each year!!
The answer is yes, David Verity is a perfect leaf bag plant and it has come back for me under that treatment in warm winters and in cold ones. This winter doesn't really count since quite a few of the unprotected ones also returned. In a pot is something special though.
