i fear the worst my hebe is well established in the ground for 5 years in a large border with the oak tree. I hope all is not lost. I have never pruned it. My cat has slept under it this year to keep cool. Can anyone help and name it please
Hebes can go like that every now and then. Especially if it's in full sun and experiencing the kind of heat we have had this summer. If you have never pruned them back after flowering, then there is no harm in doing so now. Don't prune too far back to begin with, as many do not bounce back. And if they do, they take a very long time to recover.
There are so many Hebes, so very difficult to name them, but going by your photos they are very likely to be Piquifolia or Rakaiensis.
Thank you for your help, I will try a gentle prune and see what happens
