I have a wonderful Salvia 'Love and Wishes' (bought last year) which remained in flower over the winter after the mild weather we had in London.
I couldn't bring myself to cut it back, and it hasn't actually died back at all but is now looking a bit sorry for itself - very leggy although there's still a little foliage on the woody stems. It's in a container rather than a border, if that's relevant.
Am I too late to cut it back for any new growth this year? It's one of my favourite perennials in the garden and now difficult to replace if my neglect had sounded the death knell! Any advice?
