I am resigned to thinking that they probably can’t be partners in my garden (though I am going to try – just in case). Callicarpa isn’t the problem, it’s the Verbena (will it work in zone 5? – supposedly not, but I have found evidence from other gardeners that it might).
But there is something about this ridiculously pretty purple color in hazy effect that I just can’t get enough of. Are you buying seeds that might not work where you live? I always do — sometimes I strike lucky and it is just worth the risk.
