My griselinia is dead I would say, took a beating first time around and cut it back but Christmas snow seems to have finished it off, not a sign of life.
My escallonia on the other hand is very sick but has signs of new growth. One of the plants in the hedge is totally dead, killed last year but the others kind of covered it but this time it is wide open so I just removed as much of it as possible. As there are no leaves on the rest of the hedge it is very open at the moment. Have cut it all way back and hope it will recover.
Had a lovely pittosporum hedge, fine first bad yr, killed stone dead this time.
I needed to fill gaps in the hedge, went to garden centre and they had nice big pyracantha plants, I didnt already have some, dont really like them but need something with thorns to discourage intruders, they assured me none of them were killed by the frost.
I have a plant called Lonerica, small bright green leaves, frost did it no harm, I think I will replace the pittosporum hedge with it, it seems to be very hardy and easy to trim.
