Callistemon red clusters - are mine alright?

Question from Mrs Lorna Dyter

I have two of these which were planted early last year. I have one in a pot and one in the garden. Both are in sun and well drained. I have left these out all winter, is this OK to do as I was advised that these are hardy? The leaves have gone a rather grey colour, not dropping off but not very healthy, do these drop off and new ones follow on these plants?
