Beautiful garden, lovely light. I have one of the red plants (can't remember it's name) top center and the red leaves were just coming out when we got a frost and they all turned brown. I think and hope the plant will survive but it is struggling a little.
@shirleybankfarm Thank you for your comment , this shrub is called Pieris. we had the same trouble with ours after the snap of frost , we picked out the brown leaves , and as you can see it has survived
