I have been disappointed this year because for 4 years I have had black and blue salvia return. I have had 4 to 5 plants that I have been able to keep going and so far I have seen only one plant that may be returning..I keep going out there and staring at the place where they were growing...I know they don't usually come back this far north but I have been fortunate so far...Wonder if they still may come back as I haven't seen any salvia of any kind come up yet..I usually have lots of plants that volunteer. Here I am crossing my fingers!!!
