In the UK, have tried to grow this for several years, only to get it frosted when in full bud in late October! Not at all hardy here, but over-wintered cuttings provide healthy plants for the next year.

This year we had a crazy (unpleasant) summer, with rain and overcast skies throughout June and July. This prevented some Salvias from flowering at all....e.g. S. striata and S. corrugata....HOWEVER...S. madrensis got confused into thinking that shorter daylight had arrived prematurely.....so I had a spectacular flowering plant for 2 months from mid-August! It was quite sensational! The same thing happened with the new S. amethystina subsp. ampelophylla....this never flowered before November in the last 2 years.
