Is my hebe in trouble?

One ...I think .

 

Since I lost some to frost several years ago, I never plant them in the ground now, I have them in pots. I put them in the shelter of a wall and they still died back but I think they'll be all right. They're in the greenhouse now, until they start regrowing.
Next winter they're going in the greenhouse early.

 

I only have one Hebe and its looking ok, looking around they mostly seem to have come through in other people's gardens.
The green leaved ones are hardier mostly I think.
