It one of the herbaceous salvias, my soil is heavy clay, each year they die right back but shoot from the bottom each spring!
This year as I had not cut them right back, I scratched a couple of the stems and there was still green showing!
Mind you it has not been a really hard winter here, so far!
The other thing I do is take lots of cuttings of it just in case, and as it is one of the fastest growers it soon make good sized bushes!
The others such as Hot lips etc also grown outside have not had a single causality this year or other years when left outside in the ground or in pots, so they must be pretty hardy!
