Welcome to ATP and welcome to the Agastache and Salvias forum. Happy you are here!
Your plant must have been something coming back for 5 years. You can always get another one from http://www.fbts.com/salvia-dan...
. That's where I get mine. Since it is not hardy here, I get them for spring planting. I plant it in a container and if they don't survive the winter, then I'll order another one.
