Can I over-winter Black & Blue Salvia?
My Hummers LOVED the Black & Blue more than any other flower, And even more than their feeders!! It is not hardy here in MI, The tag says hardy to Z. 7,
I wonder,.. Can I dig it up and put it in my basement like we do with Cannas? Or Is it the type of plant that needs to be green year round. I know I don't have much time to decide up here in MI, I'm surprised it is still green!!
Thanks for reading, And any and All advice,
