DigginDirt said:HI,
I have a beautiful "Black and Blue" that I would really like to keep growing for next year. The claim is it is zone8-10 but I'm in 7b. Many, including the nursery I bought it from claim it will do fine in zone 7 and possibly 6 if mulched very well.
I thought about collecting seeds as a backup and came across this article from the attached URL in which the author lifts them over winter, essentially treating them like Dahlias. I was wondering if anyone has tried this and how successful they were. I know this variety is easily found locally and not that expensive, but I would still like to treat it as a perennial rather than an annual. So far we've gotten a few freezes down to the upper 20s and it is still blooming; being close to the house & in a raised bed may be protecting it thus far.

Welcome to the Agastache and Salvias forum.

Hope you read all of the articles that FBTS had links to. Sorry, but I don't know about overwintering the Black and Blue tubers. I live in zone 6a and I just dig them up the following spring and get new plants, since they aren't that expensive.

@FBTS is offering a superior version of Black and Blue on his website and I'll just get that instead of getting Black and Blue. http://www.fbts.com/salvia-x-g...

You might want to click the link, read Kermit's description of it and get it. Anything is better than the Black and Blue we've all been growing and I'm looking forward to growing 'Rhythm and Blues'.
