Here's the kind of longer-term damage I'm talking about with the Japanese maples...
and my Hydrangea paniculatas...
The herbaceous plants and butterfly bushes look just as bad, (Here's a remant of my Black Jack sedum)
,
but any of those that survived the initial pounding can be pruned back hard and will look good again one day. You just can't prune a JM to the ground and start over. It's a waiting game now to see which branches die back and what is left to work with.
